I've been searching for information for the STOCK cams installed in the LFX engine. Spent over a week searching HPtuners forum and Google in general. The most specific thing I found is that LFX...
Have a squint at this:

That's a reprint directly from the GM service manual (Document ID# 564570)
Note the factory spec in step 2; (48-55...
Any luck finding a tuner or rod shop yet? FYI, no harm will be done by installing the switch-pin-wire right now while ur looking for someone to do the flash. The PCM will just ignore the switch state...
I installed my PerfShift pin & wire w/o unplugging. Don't worry, the numbers are on the back and are pretty easy to see.
From what I've seen, HPT is only missing the 'cruise' and 'city' tables. I...
Q. Are the diagrams here of the front of the socket (back of the cable plug), or the front of the plug (back of the socket)
A. Shouldn't matter. Just stay on the clear connector. The pin numbers...

Do that.
iirc, 01 and later command pig rich once per drive cycle and confirm that action by monitoring the O2 signal. once passed,...
Start with the easy and cheap stuff. Clean the MAF and IAC, then spray that cleaner around gaskets on the induction side during idle. If doing that produces a surge or stumble, you've found a leak....
Is the EGR simply removed or replaced with a blocking plate?
Nothing is better than solder and rosin flux and nothing is worse than clamp-on splices. Use the liquid flux don't just rely on the core. The liquid is good 'cause it seeps down the wire under the...
Geo is right. With almost no extra effort, most guys on here could get you an extra 3-4 mpg or a quarter to half second off ur ET with just a few refinements to ur firmware.
Shouldn't make any diff...
Here it is.
For reference compare the 98 and 01 Grand Prix. See how pin 21 goes from Preformance shift to not used? Well, It still works if you enable it in Tiny Tuner.
You won't have to remove the...
If you look at the first model year M-90 GTP ('97 from the repository) The IFR was flat. That is how the calibrators thought it should be with a vac ref rail. They soon discovered the #18 wire...
Gimme a day or so to look up the 2k2 Bonnie pinouts from the factory service DVD.
All this info comes from the 3800 even the Camaro stuff. The Bonnie and Prix both use the 4T65E transmission. You...
I'm very glad to hear that.
I’ve got three years of electronics engineering myself. When I said “Can’t advise you as to what the momentary switch type is.” What I meant to say is I can’t tell you or your mechanic which software...
You will definitely need to run your own wire. It’s not installed in your car. There may be a grommet/pass-thru in the firewall next to the steering column. The attached example is from a 97-03...
VCMedit beta has the tables you need.
Was reading your thread on that other site and am familiar with ur goals and restrictive zoning laws.:banghead:
You won’t be able to modify the lever/selector.

Offset vs PW vs MAP describes to the PCM how increases in pressure across the injector hold the pintle closed longer as magnetic saturation builds to a point strong enough to overcome the spring AND...

It'll be correct alright. The fuel calc uses Bernoullis flow equation. The same one ALL professional engine calibrators use. It will yield THE MOST accurate fuel model possible. That's with the...
1. Use injector data.
2. Use VCM Editor\Tools\Unit Conversion\Fuel Injector Calc
3. Ford spec pressure is the "current" pressure in the calc. Ford spec flow is the "current" INJ flow in the calc....
