Real Fiero Tech

Well if you already had wires running into the car for the other PCM, then you could save yourself some time and mount the LS/Shelby PCM inside too. While you could mount it out in the engine compartment, you will need to find a place where it is away from heat and also you would need to mount it in...

The Shelby/LS PCM you got should fit in the stock Fiero ECM location without you needing to modify the center console - DEPENDING ON how much room your conversion plug-and-play harness takes up.

Back to this guy's issue, there are SEVERAL idle control constants and tables in the 99 LS PCM/Shelby programming that can be adjusted: Idle Control Parameters: IAC Reset Park Position Idle Throttle Area Scalar Throttle Cracker Disable Speed Throttle Cracker Enable Speed Idle Adapt Enable Coolant Te...

No worries. I just wanted to express that sometimes we don't always see reflections in the scan data that we see in the end result of the way the engine is running (ie: commanded AFR in PE and actual AFR coming out of the tailpipe). Ideally it would be nice to get those two numbers to jive, but some...

Did I send you the flow sheet for my injectors? If my injectors flow 19.2345 lbs/hr at test pressure/temperature, why would we set the injector constant for anything but 19.2345 for an engine running the same fuel pressure (fuel temp varies of course)? I understand that it's *easier* to change the ...

I'm going to have WOT tuned locally... That's easy enough. I'll have to figure out how to log on the cheap to send you the info for part throttle tuning. I wouldn't do the WOT tune until we iron out the idle and part throttle aspect of the tuning. That's because if we have to change any of the base...

The guy said he took it to a tuning outfit that tunes LS's and other stuff on a DYNO. There's two big problems right there. Sure, they may be familiar with the PCM and tuning aspect of it, but they probably know nothing about Northstars; and their LS tuning logic probably doesn't apply either. Also,...

Buy a dirtymax Oh I'm already sold on that. My uncle bought a 2004 GMC K2500 HD Crew Cab shortbed with the duramax for his heavy equipment business new and has almost put 200,000 miles on it to date. They still have it. Never had a problem with the engine or trans, but it has been thru a transfer c...

Never drove a 6.0 truck have you? Our GMC has no trouble driving anywhere unloaded or with a 16' trailer hauling 8,000lbs of car(s). Torque, they have plenty of. Dont compare all LSx engines to the wimpy 4.8's or early 5.3s GM put in everything I've driven several GM trucks that had the 6.0. I wasn...

The bone stock 150K+ mile CPI 4.3/4T60 in my 88 fiero would pull down 32 mpg on the interstate Yea but the bone stock L36 / 4T60-E swap I did in my Wife's Fiero bested that by getting 37+ mpg on the interstate. Would the L36 do better in an S10 than the 4.3 could? Don't know. Haven't tried it yet. ...

My dad's Suburban with EFI Cadillac 500, 4L80E and 14 bolt floater with 3.23's will crack double digits... I know it needs tuning, though. The 3800 wouldn't make a great towing engine... fuel consumption would skyrocket if you had to tow up a mountain, boosting all the way. Oh, I wasn't suggesting ...

I've never driven a 4.8, 5.3, or 6.0-equipped GM truck that pulled a trailer or hauled a load as good as my 96 5.7 vortec-equipped truck does. What about fuel economy with the new engines vs. the old? 5.3L 1/2-ton trucks are stickered to get about 20-21 mpg hwy, IIRC. 6.0's, not so much... Can't te...

IMHO, the biggest problem with the LSx is torque, or lack of it. HP is great for bragging rights and high speed runs, but you need TQ to move the vehicle from the starting line or stop sign. When GM introduced the 4.8, 5.3, and 6.0 variants of the LS1 for the trucks to replace the aging 5.0/5.7 Vort...

I thought of that too. But if that's the case, if I didn't get taxed I could employ more people, right???

If you've been watching any sort of national news coverage the past couple of months you've probably seen the pro-union protestors in Wisconsin and my home state of Indiana holding up signs that say "tax the rich" (in order to pay for their salaries and benefits). But I have to ask: why do...

1999 was the last year for the 4T60-E. (All 3800-equipped cars quit using them after 1997). If the car is 1997-newer and the engine is the 3800 Supercharged, then it has a 4T65-E HD. If the FWD car is a 1998-newer and the engine is the 3800 non-supercharged, then it has a 4T65-E (non HD). Transmissi...

The EP376 would support up to 331hp on a N/A gas engine that has a BSFC of 0.5, using NAPA's published numbers. From published numbers... I believe that pump is also used with LT4 Corvettes with a factory rating of 330 HP, probably closer to 350 IRL. I haven't heard much about Corvette guys needing...

All of this is assuming that the specs are right. NAPA doesn't build or test. I agree 100%. And we've been over this before about different brands of fuel pump and those of the same brand and part number not being made in the same place (USA, Mexico, China, etc) and of course - all will probably ha...

NAPA Online lists a Delphi FE0113 as being used in the 1988 Fiero 2.8 application. They say it flows 14.4 gal/hr @ 50.8 psi.

Looked up one for a 1987 Fiero 2.8 and they give Delphi p/n: FE0039 which specs 18.4 gal/hr @ 50.8 psi.
