Hey Ken, I see there are two kinds of dynos used. What shop had the Dyno Dynamics? I think that's the Cadillac of dynos. Did Kan say which dyno he liked better?

 

DBPERFORMANCETUNING.COM - KAN said it made no difference in tuning the car. He did not know why people would spent $40 more per hour to use that one.

Ken

 

I have two theories and one observance:

Theories:

1) Steve tunes cars richer than others, therefore they need a better ignition system.
2) People Steve tunes generally have crappy parts, and are not prepared for dyno tuning.


Observance:

We had three cars this weekend with stock coils etc, one with new plugs/Twin Power, one with ~500 mile (track use) plugs/Twin Power, one with older plugs/Jacobs. None of those cars had any issue with ignition breakup being tuned by Steve. 370-400 hp (Dynojet numbers) at 14-16.5 psi of boost at peak hp.

 

Could you hold a load on the dyno at Hitech? What I mean by that is say for instance you wanted to tune a RPM range at varying load ranges. You would need a dyno (like a Dyno Dynamics) that could limit that car to running at a set rpm while you are in there giving it more/less gas to vary the load to give it a better tune. This can't be done on a dyno that can't hold a load or "hold back a car". I don't know if that made any sence to you or even me after reading it I'm not vary good at explaining things.

 

The second dyno was selected mainly because I wanted to compare numbers from my last session in mid-June with my numbers from this session. I used a Dyno-dynamics dyno then at LSE performance. They were unavailable so we went with this dyno.

I was also hoping to tune in a slightly different manner, but I just let Steve do his thing because he generally has good results. He said that his style of tuning works equally well on either type of dyno.

He did say that it was/is nicer to use because he can use the load balacing to make his job easier. That doesn't mean that the results would change much, just that it's more convienient.

I may at some point do some dyno tuning myself to see how my method would work out.

 

When I had my car on a dyno almost 1.5 years ago it was a dyno dynamics and the load holding capabilities really impressed me. Makes the job a lot easier to dial in the car vs spinning a big drum.

How would you tune vs what you let Steve do?

 

that's better than you spending 6hrs a day in the **** bowl...

 

Well, Steve can correct me where I get something wrong here, but I wanted to use the dyno to hold the RPM at my specified levels (400-8000 on 400 rpm increments) and vary the load to get the pressure to change all the way from the top (massive vaccuum) to bottom (as high of boost as possible) and tune each cell individually.

I would run through the entire map like that 2-3 times, and then do some runs the opposite direction, varying the rpm while holding the pressure constant.

In that manner you'd hit every cell the car is capable of hitting and tune it to your desired A/F.

Of course there's some issues with this, in terms of temperatures etc, but you'd have to set it up such that all of those other variables stay as consistent as possible.

Steve said that this won't replicate what you will actually see on the street, and therefore the map you would end up with isn't going to be any good.

I trust that he's right, given his experience etc, and i let him do his deal to make the map I will run for now.




All of that said, I would like to try my way sometime just for fun.

 

I'm sorry, but you're omitting several key factors surrounding this situation. First of all, I doubt an employee of our shop would steal your clutch pressure plate when he could get any clutch at cost. Compounded with the fact that the mechanic assaigned to your car back then did not even own an RX7, I find this to be an unlikely situation. It is most likely that it was accidentally thrown out in the process of relocating the shop to a better area. Also, you are quick to point out that we lost your pressure plate, yet you neglect to mention that we compensated you with a discount that far outweighs the value of a used pressure plate, as well as refunded the cost of a plane ticket when we discovered more issues with your car. Again, we apologize for it's loss, but sometimes these things do happen.

 

I suggest you not respond to this thread. I have already contacted Kan and I do not think you would want me to post what's going on in this public forum.

I could care less about old stuff, just that my car is screwed up after spending $16k+ on it. WOW, $95 for a plane ticket that Kan said it would be ready on the 23rd. What I should have done is let him tune it in TX. I did not know you already drove it for 700+ miles and I paid for the fuel.

I suggest you not get into it with me. It will be to your disadvantage.

Thanx,

Ken

 

Thought I'd say It was a fun day at both of the tuning events!! I was happy. LOL. Getting to see all the Rx7's come together. The numbers were great also. good HP on alot of the cars that were there.

 

...

 

Thats a mature response. My day goes more like this: 9-12 check emails, buy/sell, package/ship parts. 1-6 I do work in the shop. 7:30-9 I'm at the gym or one my martial arts classes. Thats how it goes when you're a one man show and actrually have to work. On top of that I am in school full time taking online classes. Have a great day.

 

Your suggestion is noted, but please keep in mind that I am simply replying to this thread as instructed, because it's my job to do so. As requested, I will no longer reply to this thread (unless I am instructed to do so).

 

Sorry, post #190 was me.

 

I want everyone to know I have the greatest respect for Steve Kan, I saw him in action this last weekend and I feel he knows his stuff. He took my car which had problems and found the problem after about an hour of looking at shop manuals provided by another 3-rotor with a laptop and the shop manual on his notebook.

Steve is GREAT.

Too bad he does not do all the work on the cars in his shop.

I really don't want to go into a pissing match with Steve's employees.

If things don't work out with my car then I'll just give up and live a life without a rotary,

JEEZ then I'd die, I'm only 62 years young.

Ken

PS: Many times in life my life I've been screwed - so what? I'm used to it.

 

Ken, I'm curious what was wrong with the car? Seams like you had all the right parts for a pretty potent setup??

 

Steve sent me an e-mail and promised me that he will correct any issues with my car. It will cost me if the parts that caused to problems were faulty. I suggest you e-mail Steve directly if you want to know more.

Thanx,

Ken

 

Good luck with the car. I hope you get everyting sorted out. If you were closer I would be glad to do it for you.

 

Hey B_Rock don`t use my login :P

 

Seems like you have no idea what you are talking about. So you visited Watauga and now you think you understand what goes on @ Gotham? There is a whole mess of people in Fort Worth who can give you the real inside scoop. All you have to do is put down your Steve Kan statue and ask. Steve is a whiz at tuning but he is far from a competent mechanic. Steve can port but there is nothing impressive about his engine building. I have observed these things with my own two eyes. Your hero worship has rendered you blind. 16k for 400+ horsepower? Seems like you got a deal. The problem is whiners like you who let their cars sit idle and can't decide on what they want. $75 an hour for specialized automotivce labor? They are giving that **** away over @ Gotham! I could go on and on and on. Blah blah, it doesn't matter. If you send your car to Gotham, and the mechanics build it, Steve tunes it, trust me... you are much better off that way. Everybody on these forums are crazy for steve like he's some kind of tickle me elmo or something.

 

Couldn't have said it better myself.

 

Steve Kan is the man, you guys don't have a clue what you're talking about.

 

These are 8'S on the bike and the car is 9'S.

Have fun.

Ken
