Lets Tune an IROC-Z!

[@informative_walrus]

just found you, appreciate the information. Not my car but same era

[@GulfCoastTuningandCalibration]

Absolutely love your videos!!!!

[@mikes.1882]

Victor Jr and a 700dp will fix that beauty.

[@Aqua350Lt1]

Crazy you can tune those

[@ICONBADGTA]

Not hard, just got to jump through a few more things, understand the backward thinking GM had back then... I tell anyone with the 1990-1992 speed density with the MAP sensor and no MAF to use the "EBL P-4" or convert their MAF cars to a speed density EBL.. 3 wire move i am told... No more "CHIPS TO BURN" and easy peezy, partially self tuning also and has programming for boost, nitrous, wideband, all kinds of goodies in it.

That intake is 100x better than mine lol i have nowhere to go with mine.

I know you dont use the software, but assuming you've heard about the September 16th verdict, got any opinion on future issues we likely will deal with on our platform? I'm talking about EPA vs COBB Tuning.

[@strongspeedworks]

The EPA doesn’t care about small stuff.

Get the ultimate TPI from FItech comes with 3 bar map sensor boost ready and handheld tuner and uses factory gm small cap distributor for $900 A Steal

[@yeahididit9054]

And Data logging

[@strongspeedworks]

No.

Are you on TikTok?

Negative

Did you "ZERO OUT" all the other "TIMING ADDERS" or take them into acct on the main timing table when you adjusted it? The TPI timing tables looks "LOW" at W.O.T, but it has a bunch of "ADDER" spark tables for temp, P.E, a lot of people don't know about or understand, etc.... I "ZERO'D" all the seperate "SPARK ADDERS" on mine and made the ECM run off just the main timing tables to "LOCK OUT" timing kind of like locking a dizzy out in ways... Makes spark tuning safer when first starting then you can make adjustments and add those temp, hiways, launch, P.E, spark adder tables back when you get it dialed in using just the main spark table.. I got a ZZ430 clone which is Fastburn Heads and LT4 Hotcam, 430 HP/TQ rated at GM but mine is pushing 440-450 due to more compression, 9.9:1 VS 9.6:1 GM rated theirs at... Where it is more efficient "QUICKER", I had to shoot for 12.5: 1 W.O.T to get her to stay around the 12.8 commanded P.E AFR because mine didn't wanna go below 13: 1 at 12.8 Commanded P.E.. The 1990-1992 is MAP Speed Density, sooooo much easier to tune, and if you have a EBL P4 you don't have to fool with "CHIPS" anymore... It's like a TPI computer banged a Holley and the EBL is it's "BABY"!! I had problems out of the Ford Red Top 30's, i sold mine and got some Accel 30lb, Closest running to factory TPI engines, and has 14.00 OHM like factory injector resistance vs 12.00 OHM on the Fords..

[@strongspeedworks]

Yes I zero’d out the adders.
