Best ECU For 89-91 TII Solo 2 Street Prepared
 
I have a 1986 N/A SE and going to have a 89-91 TII engine to be put in there. I will need harness and ecu. My goal is to be in the A class Street Prepared but i dont know what ECU setup i should go. I wanted Haltech for its harness since i dont have one. Yall know what is legal and not legal. I would like to know what options there will be so i can continue my project.

Thank you :)

Best one for ASP is the stock computer. Any other computer and you are in BPrepared. Atleast according to the rules.

I could be wrong thou. This is all from memory. You might want to get a Solo Rules Book off www.scca.com.

I think your right, that would through you in a prepared class.... CP or BP...

As far as stand alone ecu's I like and have the Wolf EMS, but the Haltech is great unit like wise the Tec-1 and II, but the TEC's start to get expensive and at that point I'd spend the extra cash and get a MoTec...Bar none they are the best....

If you consider a Wolf, which I recomend...The US REP. that we had, is NOT with the company no longer ( thank god).....But if you contact Ben @ Wolf AU they can set you up

i think you are ok with a fuel computer as long as boost is stock controlled. don't quote me on that though. as with anything, follow the rule book.

I went down to Rotory Performance and he was saying that i could run a stand-alone unit but he said that it could not have a boost controller on it for my racing class...Im having a somewhat difficult time b/c i like to control my ecu for better performance on the street as well as for the track (not a street racer freak--leave that to the track).... Forgot to mention this is a dual duty car but for weekend or special occassion driving on street...Any info will help me see a bigger perspective...And thanks for the help i previously have gotten...

What others have said it true. You must have the stock ECU controlling the boost, but you can have another computer running the fuel and spark, and of course other things like electric fans, etc.
But here is the part that you need to be carefull about. If you are swapping in a turbo engine you need to swap everything that is different between the N/A and the turbo; brakes, diff ratios, tranny, etc. If the subframe members are different you need to sway them too. It's possible that it will have a different (lower) weight than normal, if you just swap in the turbo engine. That is the advantage they (SCCA) are trying to discourage.
If you wanted to control boost then you could also run in the new SM2 class.
Good luck

Well its the engine and tranny well JDM swap. 4.10 rear end will be the same dont see the prob with that and i dont know how stock brakes will effect anything against the rules. But good idea running on seperate systems thanks

An apexi super-afc along with a stock TII ecu would be fine for the ASP mods.

While drag racers can get away with just about anything, good injector resolution is extremely important for road racing and autocrossing events. The Wolf3D 4.0 and Haltech E11 have a very good 0.004ms resolution, and I wouldn't consider anything less than this. Just my opinion, anyway.

I don't think that you can use a stand-alone EMS in the SCCA Street Prepared category because for one thing, it bypasses the factory overboost fuel cut. For your case it's a moot point, as that J-spec engine moves you to the Prepared category, and maybe even the Modified category. You may want to get a clarification on that from an SCCA official before you do any more work on your car.

The JDM TII is the same as US TII ???? i thought they were the same...
Thanks for all the help Aviator

He may be correct, but unless you go to nationals or something who is going to care? Corvettes own ASP anyway.

DENTONTX-RX7 12-04-02 10:53 PM

No..i plan to race around home...Mineral Wells and Bedford...but im not planning to go national....Just want to get into some competition and have fun...you say corvettes may own it but who knows :evilgrin: muhahaha :evilgrin:
