My friends in St.Louis keep blowing their motors up with Wolf computers. Anyone else having these problems. I'm talking 10+ motors. What's the problem? Lack of experience in the USA?

aki11ez

no problem here, actually quite the opposite

Gargamel

What kind of horsepower are you at? I'm talking on the larger side.

aki11ez

well i've been tuning on a s5 block with light porting to4e turbo, making 330 whp @ 16psi. I found it really easy to setup after a couple phone calls with chris. I'm currently swapping to a 13b re motor, and a gt40 turbo.

I understand that your probably looking for larger numbers than that, but the fundamentals are the same.

a car im tuning now, is showing some symptoms of trigger interference, we're tracing it down now.

you might wanna use the maps i posted as base maps. thats the setup im currently running tuned perfectly at 20+ psi on 93 octane =]

aki11ez

lol, 20 psi is just insane on pump gas!! what is your timing at 20 psi?

Evil Aviator

Yes, I think you hit the nail on the head. For some reason people don't want to have a professional tune their car, and they think they can do it themselves with a wideband O2 sensor cure-all elixir.

Actual map from somebody who thought he was a tuner just because he owned a shop and had a wideband O2 meter:

You live in St.Louis now? The person I'm talking about is Gary Hagner, if you can tune his car then we need to get you two hooked up. I'm tired of rebuilding his motors

Evil Aviator

Yes, I just moved a few weeks ago. However, I am not a tuner.

aki11ez

lol that's funny the "proffesionals" i have run into have either sat and "spun their wheels" while accomplishing nothing, or are completely pompus and starting punching random figures into boxes because it didn't "look right"

I guess we all have our different opinions of "proffesionals" but from my experience is to study study study, do your research and tune it myself. It's worked out great so far with my car, and now on the second car I'm helping tune, i've become so familiar with the system that I can tell when the car has a non-ecu related problem, because the ecu isn't making the changes that it should.

I'm sure the proffesionals you are speaking of are not this incompetant, but just because someone claims to be a pro, isn't always the case.

oh my god.


look at the advance on that ignition map? no compensation in the fuel map for torque peak or anything...

nyt

iTrader: (1)

how do you figure its insane?

i have no issues with it. 13 advance @ 20 psi with 10 degree split.

tune your car right, you can run boost =]

Gargamel

My friend is running 15 degrees before torque curve and running lots of timing before 8psi. He did this because he thinks it will increase his torque.

nyt

iTrader: (1)

15 degrees at what boost level? i posted my ignition maps and pictures of them plenty of times.. nothing special.. safe maps, work well.

aki11ez

i have my car tuned spot on, your timing curve is much more aggressive at high boost though. I'm only running 2 degrees that high! At my max boost now (15 psi) I'm running about 9 degrees of advance.

aki11ez

jebus! If that is a safe timing map, then i'm probably missing out of 50 hp.!!

Gargamel

Do you know Ryan Scott? I think he was telling me about you, he said that you "WERE" a tuner

Evil Aviator

I talked to Ryan on the phone, but I have never met him. I would like to have attended the BBQ a few weeks ago, but that was the day that my household goods arrived.

Yeah, I can tune an airplane engine from the cockpit (fuel mixture, not timing), and I can show you how to do that on any flight that you take me on.

Seriously, I am not a car tuner, and I always have one of the "smarter" guys tune my cars. Sure, I know a lot about tuning, engine performance, theory, etc., but I am nothing compared to the REAL tuners who tune my cars. Unfortunately, I don't know anybody in St. Louis yet, but I am sure there are some aviation mechanics with rotary engine knowledge hiding around here somewhere. Also, my RX-7's are still in Florida because I will not have any place to work on them until I buy a house sometime next year. I'm not sure if I can even bring my 1Gen to St. Louis (as a street car) because there is no way it will pass emissions, and it's not exempt until 2010.

Gargamel

I know how to get passed emmisions. Gary was able to get his waived. Simply tell them your running alcohol. He did this and it worked without any questions. The can only test gas.

With 94 Octane at 15 psi: I run 17* advance until peak torque, drop it down to 14*, then ramp it back up to 16* until 7500 rpm.

With 91 Octane, it goes 14*-->12*-->14*.

I'd been running this map for about 2 yeras. Steve Kan looked at my IGN map when tuning my car in November and didn't change a thing

ULTIMATERX7

I am not an expert tuner, if I could get an expert tuner here I would pay to have him set up my car. The tuning I do with my car is very conservative, low boost, and low timing. I run my timing flat across the load bands, 18 degress at 10 psi and 15 degress at 12psi and 15 degress thereafter. The last time it broke my fjo wideband data logged 10.6-10.8 running 12psi. Any help is appreciated but it looks like I'll have to find some tuner to come here. I will not drive my car out of state, for worry that it will brake and I will have to tow it back. I am not looking for sympathy my friend Eric is just trying to help, besides I sure I am not the only one that blows motors. If anybody wants to help I will post my latest map. Thanks

post your maps up I'll gladly take a look. If you were running that rich, the only thing I can think of that would have caused that is either an ignition error, carbon buildup, or plugs that are too hot.

which plugs are you running? how many miles were on the motor? what turbo/intercooler? what are you using for ignition?

Gargamel

I'll try and answer some of the questions. Not sure when he'll get back on. Motor has no more than 100 miles on it. Ignition, 3 msd 6a's, 3 msd coils, and ngk 10 plugs. He has a T04R turbo with the Blitz front mount intercooler.

which MSD coils? I've had horrible luck with them. In fact, I run regular turboII coils in all my cars with great results. I use a 93 igniter with an msd 6a on the leading coil.

I actually had a set of MSD coils in my FD (Bridge port, etc etc) and had to take them out because they didnt provide a hot enough spark to run high boost and actually decayed in a matter of months to the point where you could barely get into boost. I switched them out for tII coils and the car runs strong as hell now.

I'd still like to see his map
