never heard of it.
gimme the website and i'll have a looky--but even then i wouldn't be able to tell you anything useful, just curious.

the ones i've used are :
my current techedge--love it
old fjo--hated it really slow reaction time and the dim green display is almost invisible in the daytime
innovative- didnt' like the features too much, but ok quality

i haven't used, but have heard nothing but good stuff about the new fjo, and the plx unit.
whichever one you get, get one that uses the bosche lsu4 sensor. very cheap, and good reaction time.

this is the wideband that is up for a group buy here with the club.

here is the group buy thread

 

that thing looks like it's worth a go. really inexpensive for the features.

 

And i would like to know what happens if your "free tune" includes a "free blown engine" then what?

 

i know about tuning...it's the interfaces i wanna get comfrtable with.
with how conservative i do things, if the engine blows, it won't be from the tuning.

 

dude i would not let you touch my care...ever. I would not let somebody "tune" my car so they could get used to the interfaces of the software of the ecu.

What would you say if the engine did let go a seal etc? Oops sorry?

 

afr's and egt's don't change from system to system.
it's fine if you dont' want it... i don't care.

 

If you've got the tools to monitor/measure the combustion process, and the knowledge to understand this and know what to do with this info, then why does it matter whether you have to learn the software or not. Everyone starts somewhere, and I can vouch for Dave on his tuning.

 

thanks.

some people don't really undestand what tuning is...

 

Don't tell me what i understand or dont understand Dave. You dont know me.

 

same applies to you.
if you don't have anything productive, stay off the thread.

 

guitarjunk, can u help me tune my SR in my FB?

 

You didn't answer the question.

Are you bonded and insured?

What kind of warranty do you offer?

These are things that people may want to know before letting you tune several thousand dollars worth of engine. If you will not back up your tuning, then the members of this forum should probably consider just letting you watch while somebody competent tunes the EMS. I am sure that someone with your stated tuning experience can easily learn a new system by watching with your eyes and not with your hands, and it may be to your advantage to keep free of any tuning liability.

 

Thats exactly what i was trying to say and did say in a different way.

 

user interface for a haltech is different than a microtech is different than a pfc, etc...
getting familiar with the different kinds of interfaces is what i wanted.

low blow on the competence...
i wasn't aware you had to be bonded and insured to do someone a favor.

 

Competence includes both tuning knowledge AND system knowledge. The entire purpose of your thread is to attempt to gain competence in other systems. I don't see how this is a low blow when I am only restating your own assessment of yourself, and I don't see what is wrong with wanting to learn something useful.

You are still not answering the question, but I assume that you have no bonding or insurance, no warranty, and your answer to any blown engine is to blame it on the engine construction. You could have simply stated this on the first page of the thread and saved everybody, including yourself, a lot of typing.

 

now that's a load. don't imply things i didn't say. if a bearing fails, i'd see the engine builder, but if an apex seal goes, it's most likely the tuning.

and do i have to be licensed to do something for free? i seriously don't see what the big deal about learning new systems is. the way i tune, there's not much chance of something blowing--except if my wideband or egt decided to go cracky-in which case i don't know what would happen.

 

You cannot properly tune an engine armed with only an EGT gauge and a wideband. I don't care how good you THINK you can tune, without a dyno you're only making wild guesses. There's a lot more to tuning an engine to correcting base fuel tables. The real power gains are found in optimizing the ignition tables, and is also ironicly where people go wrong and blow up engines when they don't have the necessary equipment and experience to safely tune an engine. The only way to safely and correctly optimise fuel and timing is on a dyno that can measure the result of such changes in A/F mixture and ignition advance IN REAL TIME.

Look at tuning a car the same way you might look at having a toothache dealt with. You COULD see a dentist, who'll use his very specialized equipment to apply anestesia (sp?) to make you comfortable, remove the source of discomfort (cavity, decay, etc), repair the damage to your tooth (teeth?) and ensure you'll feel good enough that you'll forget your tooth ever hurt in a day or two. You COULD ALSO let your buddy fix your tooth by boozing you up a bit to make you comfortable, drill the offending chopper with his Dremel tool, and fill it with a little epoxy. This could save you a few hundred bucks, and it's possible that it'd be relatively successful. On the other hand (and far more probable) the tooth could shatter, become abcessed, etc and require oral surgery to remove/replace the tooth to un-do damage done by your well meaning would-be dentist friend. Where's the savings then?

Having somebody tune a car cheaply is a gamble, folks. Anything done for free is most likely only worth what you paid for it. . . . NOTHING!!! I'm not advocating throwing your entire savings at a tuner, as there are very few besides myself (and maybe Enzo. . . heh) that I'd trust to not blow something up. But just keep in mind that you'll spend a lot more money replacing an engine that some well meaning "tuner" blows up trying to tune for free than paying somebody who knows what their doing to tune your car right in the first place.

how do you adjust ignition? myself, and everyone else i know uses an egt.
and you think you need a dyno to tune? it's helpful, for lots of things, but definately not necessary. and with the quality of the equipment i've seen at most of the dyno places i've been to, i'll trust my own stuff.

 

You know that, I know that, and enzo250 already tried explaining that to him. However, I'm not sure if that is in the scope of this thread. The guy simply wants to experiment on tuning different EMS's without incurring any cost or liability. The method used to tune isn't really a factor, and besides, most cheapie tuning doesn't involve a dyno anyway.

Friends go a long way, and usually work for free or for cheap. My 1Gen RX-7 was tuned by an A&P maintenance instructor with about 2 decades of rotary engine experience. I think the key here is to balance risk vs. price.

 

no good deed goes unpunished. i swear

 

The good deed would be somebody allowing you to participate in the tuning of their vehicle. Not vice versa.

 

it goes both ways.

 

i was going to comment but i'd rather not.
