TPI Transplant has not run right in three years?

i think you're going to end up starting over with a new, factory BIN rather than trying to figure out how to unscrew the current calibration that has been generated based on hardware that is acting differently than what a multi-port MEMCAL(or at least converted to MPFI) will do.

Already started a new bin, not going to try and fix a turd!

Just got done soldering the V8 Truck TBI memcal. Seems like the best route with a G1 adapter on it!

Gladn we have a Collage Electroics person to edumacateus da right way!

But the 305 would be wrong Knock Module? I'd need the more rare (read... expensive) 5.7L... did the F car ever have a 5.7L or just the Corvette?


Hey, I just thought of something! Didn't these come with large Cap HEI Distributars? This has a small cap so there's another adjustment!

Mark,

All I have ever used on the 305 and 350 in my G20 van was an AXXB or AXXC memcal and only used a 305 knock sensor on both. Never bothered trying to find the 350 memcal or knock sensor. Not worth my time or effort since I turn all but 2* of knock retard off in the calibration anyway.

Well fired it up today on the truck TBI Memcal, G1 adapter and a new bin off the AutoProm. Runs great! Hoping for no rain tomorrow to do some data logging!

Found out the injectors are 25LB 2004-2005 For Crown Victoria? How am I supposed to get data from them.

Websites seem to indicate they're 24# Cobra injectors. Crown vic seems to use orange or grey injectors.

Might have to open a factory calibration to get Ford data then use magic to convert to GM data entry cells.

I seem to remember some discussion on Greg Banish's site about the relationship between Ford slope and breakpoint to to GM values. There are spreadsheets around IIRC but I don't have any. DSTech says he posted a locked spreadsheet on hptuners. This thread has info but you're likely to need help from a math guy. http://www.hptuners.com/forum/showth...te-and-Offsets

If no solution is offered by tonight I'll see what I can do.

[EagleMark]

I got a couple hours into the math and all I got was a headache!

[1project2many]

Sorry... kids decided they wanted to make mom's life miserable last night. Dad to the rescue...

[EagleMark]

Super Dad!

Moms back still acting up? I remember my back issues and surgeries when Jesse was young... man it's hard enough to keep up let alone with back pain!

[1project2many]

Yep... Mom's often sore. It's muscles. MRI shown nothing wrong in spine. I double checked the doctor. ;)

you know the flow benching machines that some injector shops have, and i've seen that with a practiced operator, they can be used to extrapolate voltage offsets and everything.. they just vary the voltage coming in, check the difference in flow rate at a few points, then build a curve.

one of us needs to build such a machine, then do injector analysis on the cheap (ex. mail an injector and $20 to this address, and get back a real-world data sheet in a day or two)

if nobody else is up for it, i'll attempt it, but i'm in canada so it'd be inconvient as a service for you guys

even the mfr's original data may be skewed from the age of the injector; and pulling from a stock cal is sketchy too, hell EE has three different offset tables for the stock 24lb injectors! who knows which one would be close

[1project2many]

Mark... Here's some data to look at. Found it while trying to locate OEM calibration data.
