Of course my 2.2 and greater 60' times might not lend credibility to this, but with 10 year old GS-C's putting it down, I thought it worked ok. Seemed to work better than lower rpm launches that either broke it way loose or bogged down (which seems worse for the clutch).

Tom, so your shift light actually comes on? Mine doesn't seem to and I thought later GM ECM calibrations didn't turn it on anymore. But maybe I just have a bulb burned out...

This techinque will work quite well....I just don't like having to replace the clutch all the time.

I know with my aftermarket chip I lost the upshift light which made me sad I'd like to find a way to get it put back in.

Thanks guys, Kevin, Bob & CAV!

Humm, I never thought about a chip turning off the shift light Bob. The chip I bought is just the replacement update for the OEM 1990 chip. Yes the shift light does work. I guess your bulb could be out? Maybe you have an aftermarket chip? Also thank you for sharing what you did at Englishtown. I hear ya about the GSC's, mine were old & hard & I replaced them with D3's.

I guess I worry too much about the IRS, too many parts & no place to work. The stuff sure looks nice though! I hate to say this but I'm still partial to the detroit locker in my Mach1, that would do the trick in the launch department!

Once the clutch is engaged & the speedo says something I have no quams about lett'in her rip, it's fun! I guess I'll never be a drag racer!

Thanks for sharing Guys!

At Carlisle last Summer on the road course I watched a C5 Z06 hit it every time he was on the course. My friends ZR-1 had lower times, won his class and never hit the rev limiter once.

As far as I know it's the stock chip. But the owner before me did buy the updated GM prom to fix the idle thing. I have the original in the GM box the replacement came in. I've never seen the light on, so I suspect it must be burned out. I guess I'll have to fix that sometime...

that tends to happen with a 7,000 rpm redline

For anyone wondering what it sounds like, here's me hitting the rev limiter in 1st gear. Not intentionally...

Hitting limiter ~1.5MB

tomtom72 · 01-15-2006

Okay I know now that I have never let the rpms get to the limiter...I must be early enough at shifting in 1st & 2nd to stay off of the limiter...I guess if you use the shift light there must be a few hundred rpm cushion or I would have hit it for sure...the motor sounds so sudective up top I get mesmerized by the sound & almost forget the shift light!

Man that thing sounds sweet, Bob!!!

Aurora40 · 01-15-2006

Well then here's me not hitting the limiter.

Oh, apparently the shift light was taken out of later programs. Though, you bought the latest PROM for 1990, right? And yours still works? I guess I'll have to pull the dash and change my bulb...

Not hitting limiter ~3MB

tomtom72 · 01-16-2006

Okay I had to think about this. I bought the GM updated Prom, code ABYK, from P & G Chevy. I had the 1990 OEM PROM. I looked after reading the TSB over at the Reg site & my symptoms matched so I put it down on my list. I know the shift light worked before I swapped PROM's and I know that after I did my plenum stuff I put in the GM/ABYK coded PROM and the shift light still works.

btw, Bob it sure does sound nice...sweet music you're car's making! You must be
