--Haltech vs Microtech--
 

MVA Motorsports states that Haltech has an ongoing problem with their injector drivers going out all the time. They state many of their motors blew due to Haltechs driver inefficiency. MVA claims that the Microtech LT-X has more than 4 drivers that decrease the chance of engine failure. The question is, "What is the odds that the drivers are bad on a brand new E6K?"

I called friend at Haltech in Texas, and he had a totally different view. They state that they never have had a high return rate for warranty. That the drivers almost never go bad. They stated that it is highly unlikely that anything happened to a Haltech unit that was properly installed and tuned. Closing the comments, they stated that he bets his job the computer is fine and is fully operational. And that if it wasn't the bad installation, inaccurate tuning was the culperate AGAIN.

What do you guys think?

Who is MVA?

I have two E6K units and one has been installed since the summer of 2000 and has been used in a road race car. I have had two problems in the last 2 years and only one was not my fault. first problem I had was the ECU was mounted to the firewall and it got overheated since it was to close to the exhaust and it quit working. Overnighted the ECU to Haltech they fixed it and sent it back overnight no charge. on the second unit I had, it was having a problem reading the rpm from the Mazda CAS, again overnighted to Haltech and unit was sent back quickly(not overnight as before ) and again no charge. I have used both of these units in the most severe situations out there and they have always performed as I have them tuned. never had any engine problem that was not the result of a tuning problem. I have made miscalculations but the ECU has always done what I have told it. I have used these units in the rain, freezing temps, and over 130*F operating temps with no problems. the one time it overheated the case was so hot I could not touch it for even an instant. If an installer is blaming the manufacturer for a defective unit and recommending another unit because of this I would be suspicious of the installer. If there is a question about the ECU send it to Haltech pay them to check it and back charge the installer if it turns out to be working correctly. unfortunately this may take a couple weeks but it may give you peace of mind. In my experience most people have problems with the installation and tuning not the parts or equipment inside the ECU. I have a racing friend who has used a Haltech ECU on his Porsche 914-6 racecar for more than 5 years without any problems. looks like a smoke screen from the installer or tuner

Your not the only one who told me that. From what I'm learning, this maybe a sales pitch from them. The unit was brand new. MVA didn't even check it out. After the motor popped, they pulled it out and said "It ha s to be an injector driver, it's always that." Honestly, they had a real difficult time setting the timing. It wouldn't suprise me if that also had something to do with the bad tuning...

MVA = Marcus Acosta?

Sounds like a smoke screen....

Yeah, it's becoming another bad deal. Anyone one else want some money out of me?

the hardest part of installing, tuning, and buying a standalone EMS is the after purchase support. this seems to be the most encountered problem. people sell them and don't know how to install or tune them and people buy different units and don't understand how to tune them. if they are claiming a bad injector driver caused an engine to fail then I would be asking why they were not monitoring air fuel ratios or EGT while they were tuning this engine. and why they did not shut it down when the EGT or A/F ratio was off the scale. engines can and have been tuned without blowing them up. I would suggest to them that they need to repair the damage that they have caused or I would seek out a small claims case. if a shop is tuning an engine correctly they should see the problem and shut down the engine before it is damaged. good luck and I hope you can resolve this.

Thanks. After my engine is repaired, I will seek out legall issues. I'm sure atleast $1500 will be settled...

Just to answer the question, the E6K has 8 injector drivers with the extra four being simply turned on in the software if they are required. Dead drivers are very uncommon.

I am very very sceptical of any workshop that will say an MT is better. It is good for the money, but it is defintely no high-end system. Any tuner that knows what they are doing will spend 5 mins with both systems and tell which is the better one. I am not bagging the MT, in fact I tune about half a dozen of them every week and some run quite OK, but what I am saying is that they dont compare to the E6K.

Well to answer alot of your questions... MVA is a dope ass rotary shop in Hackensack New JErsey... I just got my 3rd Gen out of there like 2 weeks ago with the microtech and is running f*cking unbeleivable. I know its early to say but this shit is working great for me. You guys shuld really check it out. Wanka I don't know who U R but mayB u need to come check out my car. I was in HIN in atlantic city and on the way back I had some nice kills including a viper. Therefore I think the microtech is doing better than cuttin it. I dynoed over 550 at 25 psi on race fuel with my t78. If any one needs more info on this shop hit me up. P.S. Wanka Y are U hating on the fastest rotary shop in the east coast !?!?
Rotary for life !!!

I agree 100% Carl won't admit he had his wastegate spring at over 17 pounds and when he was backfiring he was beating the car to death. When we having a friendly run luck?:D

hehe carl's car(when was his) is shit its a joke
for him to badd mouth mva he should be hung i cant stand people that say one thing and talk about people behind there back.
m.v.a is the rotor shop in jersey

supp lucky nice meeting u at hot import nights ure car is sick power
i talked to ryan(mva) that night.he stopped by my car that night he
mentioned ure car had crazy power.ure car is proof of micro-tech.
and also why marcos will go 6'sec.this yr. shhhh.

dariative i havent seen ure car run yet brother,but i heard u were stock.(yeah right)lol.kick juniors awd ass 1st.

I have a question. Where is your E6K ECU now wanka?
did you leave it with MVA?

If so, Is your supposed 'defective' E6K the same one that that MVA is selling in the parts FS section?

https://www.rx7club.com/forum/showth...threadid=87985

Hmmmm. makes you wonder....

was the ecu defective (and they are knowingly selling a bad ECU)?

or were they just telling you it was bad so they could sell you a microtech? (and not pay for the motor they blew)?

or mabye it's just a coincidence?...........
you decide :)

Kel: go on a diet.

Speed NYC: The computer was sent to Haltech (USA) in Texas. As you guys guessed, it was in perfect working order. The engine failed due to poor tuning. Was it on purpose? Was it because they knew, I'd need to get my engine rebuilt at their shop? There isn't anything wrong with the microtech computer. There isn't wrong with the Haltech (from my current knowledge). But to tune the Haltech wrong due to there preference of the Microtech is pure ghetto.

But then again, MVA doesn't always work on your car. (They have to work on their race car most of the time) They have some idiot named Ryan "learn how to" wire up stand alone computers on a few of the customers cars. I guess you have to learn somehow, a few people have to suffer from there training.

Luck: dont forget about the supra they installed the microtech on. The car couldn't even drive normal without problems. Your friend Mike wants to sell his car, due to poor work. Then again dont blame MVA, Ryan did the computer install...

Re: --Haltech vs Microtech--
 

Haltechs are quality units. in eight years of tuning i have only ever seen one faulty and it was a crusty old F3 in a range rover. It was well over 8 yaers old. Haltech Australia repaired it at no cost. With an autronic you can short the driver output to 12 volts and leave it like that. It is fully protected. Haltech are no fools and i would think their boxes are the same. Something is not right.
Very small TECH does not rate a mention.

Chris

Amen.

So the '1 month old' E6K that MVA is selling IS your old E6K that MVA said was bad??

why dont they put 'just tested ok by haltech USA' in the AD?
still dseems shady to me....
and untill now, i had only heard good things about MVA.

why are they selling it instead of you?
or are you just having them sell it for you, because people tend to stay away from parts that have been on your car?

Roan

The car now belongs to someone affiliated to MVA. From what I heard, they attempted to fiddle around with the E6 internals. They fried it,and later installed microtech. I know they don't sell Haltech, so I don't know where they are getting this E6K unit to re-sell.

Let me jump into this conversation. I am the new owner of Carl's mistreated, 5 motor blowing RX7.

We must all agree that part of a car blowing motors left and right is also a due to the owner being an inefficeint driver(atleast in Carl's case)

The haltech that Carl had installed by the shop WAS NOT SOLD TO HIM BY MVA. He purchases the unit on his own.

Carl I am amazed at your ability to bullsh*it and badmouth a shop and not allow them to counter-argue your insinuations.

You want an answer as to why you blew your motors so many times...I'll give it to you!! You are running a T88 Greddy turbo system with a stock fuel pump and stock fuel lines.......its that fu*cking simple. The car is starving for fuel. You were told many times to upgrade your pump and you refused to do so. Come to think of it I feel really sorry for my friends at nemkiv.com now that I sold you that supra........

Flame on!!!

why would any professional shop do all the installation and tuning on a car with a known problem? sometimes tuners and specialty shops need to refuse work if a customer is unable or unwilling to do the job right. If the fuel system is not right how can they say they tuned it? these are problems the shop could have solved before engines were blown "many times". Same thing with installing products that the shop does not support, sell, or service. I realise the shop was probably trying to help out a customer, but most times these things backfire on the shop. telling a customer to upgrade there fuel system and then "dyno tuning" the engine is not smart and leaves them exposed to this type of bashing. the customer is thinking they tuned the engine with the fuel system problems in mind and it should be ok until I can finish the fuel system. I don't know MVA personally, but I have seen friends of mine run into the same problems doing similair repairs. As always when looking for a tuner look for someone who is familiar with your system(which ever system it is) or is a factory authorised dealer. ask some good questions ask some former customers (if available) and do not judge a shop by there racing success or number of magazine articles. these cars tend to be built alot different from the day to day stuff in the shop.

"why would any professional shop do all the installation and tuning on a car with a known problem?" Because Carl insisted on it!

"sometimes tuners and specialty shops need to refuse work if a customer is unable or unwilling to do the job right." This is a business......not therapy.


"Same thing with installing products that the shop does not support, sell, or service. I realise the shop was probably trying to help out a customer, but most times these things backfire on the shop. telling a customer to upgrade there fuel system and then "dyno tuning" the engine is not smart and leaves them exposed to this type of bashing." He was told about the situation before hand and he said he didn't want to spend money on a fuel system. We tuned the car the best we could given the situation we were in.


"I don't know MVA personally, but I have seen friends of mine run into the same problems doing similair repairs. As always when looking for a tuner look for someone who is familiar with your system(which ever system it is) or is a factory authorised dealer." MVA is a factory authorised dealer for haltach and microtech. Checkout the MX3 on haltechs website.

It's funny how the shop always gets blamed when the car goes bad.........If any of you know Carl personally you know this is not the case. Customers get what they want. A customer is advised that preceeding his way will cuase him problems and if the customer persists on wanting things done his way then guess what? It's going to get done his way. After all it's his car.........


There are a few MVA customers on this forum that are very content with the service they were given so one dissatisfied Carl, will not hurt MVA. 99.9% of our customers are very happy with our service becuse we go the extra mile to get their cars running well.

Amen!

That is one of the most BULLSHIT excuses for fucking a customer over.&nbsp Even though it looked like th customer was "wrong" in this situation, the shop should not have the attitude to just take their money cause they insisted on it.&nbsp Business morals have gone down the shit tubes because of this crap...

I would clearly refuse a job even though the customer insisted they would pay.&nbsp Maybe this is why I don't make as much money as these guys?

Sorry for the rant - this kinda crap really pissed me off.

Hmm... Yeah.. Lets tune a car to blow up... What was the purpose of 'dynoing' the car if you knew the fuel was not there? There was never a chance the car would ever run right, but they took his money for dyno tuning anyway...and motors....and ecu's....But Wanka, you should realize now that you also can't just do a half assed job, the car and all its parts have to work together..Max

Carl only blew 1 of his 5 motors while at MVA. You guys are assuming that he had all the mods installed at this shop and thats not so.

All the shop installed for him was his 3 msd's, a reman motor he brought in and the haltech that he also brung in. Nothing else. So don't talk about the shop taking his money.

Carl was very misleading on this list with regards to what MVA was actually installing/servicing for him. I can see this is useless. No use in me continuing on with this thread. There are those that will always find a 5th leg on the cat.

Later.....
