I've decited to get myself into more mess. I've messed with the injector flow rate and constant. And it changed everything. The reason I did that is because after a while in close loop..the ECM tries to overly lean when in RPM...IE..if Short term is at 80 at idle..if you rev the engine to 3K rpm..it will overly lean the mix till the rpms drop and stall the engine. YOu have to keep stabbing the peddle to keep it alive. I have messed with the DE tables to no avail. I could not find a DE table based on RPM..just map/delta map, NMPH, delta throttle, number of injects, and coolant DE. Yea..I found the TCC DE and TC OT DE..useless.
In open loop ..the car runs verry fine. WHen it hits close loop first..it works great...then I see the ECM lower the Short term counts sloowly. 128, then 127, 123..till it goes to the 80s . It pisses me off. O2 at fist few sec of close loop is at about .6. Then when the ECM does its thing..it bounces around .3 to .8 when doing its learn thing. You stab the peddal to 3k rpm and O2 goes from .8 to .4 and lower to .3, .2 and you see the BPW and DC just drop like a rock to .1 and lower stalling.

Im thinking..maybe its a fuel pressure problem? What do you think? What PSI does the fuel rail work with thise GTP injectors at idle and at WOT?

If all else fails..I will install a 3bar map sensor to see if it could offset the large injectors.

I got the corrections done for my Win Bin ECU file. IT TOOOK alot of homework from myself. I did some hit and miss and some studing from looking at the 58 code mask and looking at my 8F document.

First table... 0654 INJECTOR CONSTANT. Used on fueling on launch mode..

This constant at first looks like if you set the Decimal higher or HEX higher..the injector rate should too. NOPE. I found this out accidently and from frustration. Largest injectors in the CODE the 8F can support is about 44lbs hr.

To figure it out I knew 178=22lbs. Simple..do conversion math and find the factor...right....well almost. 291=36lbs..but why would the base pulse increase during crank and idle..but lean TOOO much part throttle?. OK..lest work backwords.. 178 is the Center..SO if I increase the injecotor 14lbs..then decrese the decimal to get the factor to show 14lbs less than 22..which is 8. Burn chip and plug in..BOOYA. WORKS. Starts out at .3-.4 and corrects better at .2 to .1. when in close loop. Still in need of fine tune.

OK now for the Flow rate. 712 decimal=22lbs. OK or is it? I see Gal Hr on the Syty code. Why would you have two tables with the same purpuse? lbs hr..why not just one? OK this must be Gal hr..not lbs hr. Might not even make a difference if you scale it for ither. 22lbs hr (mass)= 231CC min (volume). This is all the same wheight in fuel. Not alcahol or watter. Gas has one mass and volume..so now I know it. OK now I need to find Gallons an Hour from CC min. 231 * 60 (for an hour)= 13860 CC. 13860 CC = 3.661425 gal hr. And to get 3.661425 from 712 decimal is devide 3.661425 from 712 which is 0.00514245...
I don't know if this table is backwords also..but it doen't seem to be. I didn't see a fuel sub rutien based on flow rate...only Inj Constant.

So for Injector constant I would have my table next to me. Even if It displays only decimal or is factored to display lbs hr. My chart corrects it.
On Injector flow rate...the Factor is .00514245.

Feel free to add this to your PAID definitions..  :lol: . I heard most all are still outdated  with wrong factors or non. :wink: . And I better not see my work beeing sold as someone elses credit. Give credit where it's due.  8)

More of my code to crack. I will release my definition file latter on..if I decide. :?:

So bust out those 44lbs if you have them.  :twisted:

BTW..this kind of stuff I will only post here. If someone else wants to see it..COM' GET IT.   :lol:

Damn dude...looks like you are getting in deep! So what is your current setup? Turbo? Head or intake upgrade? Any components to fool the stock monitoring sensors?

I hope you are ready for me to pound you for information this spring!

I have gotten partial permission from the wifey to buy:

T3076 turbo
Gen III heads and intake (porting done by friend = free)
Build Getrag 282 or F40 6 speed
SPEC clutch and lightened flywheel
Injectors (poundage size to support above items)
Large FMIC and custom piping
smaller A/C condenser to allow for removal of stock intercooler and direct piping to new FMIC
Complete refurbish of suspension components

Also looking into a Coil On Plug (COP) setup that would work!

Coming soon to a TGP near me! :wink:

Pilot,

Ahhhh quality time together with the Top End Swap(s) :shock:

My current setup is not too wild. Its a reringed '94 3.1 shortblock with Chrome moly rings, Crane 260-2 cam, Ported heads ,ported manifolds, ported-n-patched  :lol:   x-over pipe, 87-88 Ford T-Bird Turbo IC (temperary), '00 Duramax IHI GM-8 turbo, 3in down pipe, Oversised Ebay BOV, 36lbs Injectors off GTP, Ported fuel rail, Rebuilt ''Race" 3t40 tranny with 3.33 gears and 2200+stall, TCC lock overide and some minor upgraded hardware, Battery located for more traction, self moded AUAF code.  Just minor twiks.  :roll:  I've yet to prove the combo works (time slip).  :?

Yours looks like a good combo. Should be good for 170hp Crank N/A. More with a cam. Then add spooli thing  :twisted: .

I'd shy away from a light fly wheel on a heavy car. Launch would be a dog. This comes from Ford Taurus SHO guys. Then again..we have the torque to do it.

COPs..Well coil on plugs..that would be nice. I can only see a crank trigger and stand alone box doing it. Unless you plan on using the same ICM but wire the COPs to it and still retain waste spark. Kinda defeats the whole purpose ... :?:   :lol: .

Just an update. I pulled out of the drive way last week and it was bucking and stalling like no tommorow. It would act like it was running out of gas. I took it to a paint shop and had it painted. When I got it back I had dataloged the car. It looks like one of the injectors is leaking. IDC at 600rpm is at .29 and shows rich condition. I rev it to2k rpm and seems to lean out coorrectly. But about a few sec in 2k to 4k rpm it starts getting rich. I pulled the plugs and they showed nothing normal except the two front ones. They were ashed black indicating a rich condition. Next day I pull them out they were wet with gas. I guess sometime when it was sitting the injectors got bad. THen again..when I got them off the GTP where were already off of the motor just hanging on the fuel rail exposed to the elements. I grabed 3 more GTP injectors and I'll see if I can reprogram the engien again. Right now it has the stock 22lbs and a Jeff M. top gun to just move it around.

Good work, please keep us informed on your progress.

Thanks. When the tranny comes out..the injectors will get changed. I've been wanting to tune also for E85 with gas mixture to see how it will act. The other one I wanto try is with -ather since it has a lower BTU but has more oxidants to burn fuel more thought.
