So it should be 895C at that address?

As for MUT00/01, I'm not sure what you're asking. I fished the various discussions for the XML code and 00/01 settings. I have no idea of what works and what doesn't. It's quite convoluted to me at this point.

How are you hitting those kind of loads with a stock framed turbo? I have a really high strung heavily ported IX turbo on my VIII and I am hitting around 320's.. (And this is on E85, on 93 I was in the 300 range..)

Is there part related problems with the car as well? Everything in good working order?

To disable fuel cut I would open the boost limit table and highlight the values at all RPM levels and hold + until it all goes to max at 319.4 (IIRC). Set the timer to 10000. I suggest these simply because they've worked for me. It maybe this isn't your fault and that you have a spark related issue that feels like a fuel cut?

The lean AFR on spool up at 100% IDC seems odd. Given you have a high reported IDC it doesn't sound like it is anything to do with load, airflow meter calibration or lean spool settings. I would think you're questioning the wideband reading or the fuel system? If it is a misfire I'd expect you'd see rich not lean.

Good luck with it!

AFR: definately either your wideband could use a recal or your fuel pressure has dropped drastiacally. Maybe a simple way to check your WB would be to check your NB readings. Do they make you think the car is way lean or way rich? I'd guess that if your WB is going bad (They tend to read lean when they go bad) then your NB will say you are running crazy rich. If its your fuel pressure then your NB should say you're running crazy lean.

Ted, if you can't get a stock ECU to work then I feel for you if you throw an AEM in the car. Good luck, you'll need it!

Did anyone notice in his screenshot of his MUT table that his last three 2-byte entries are FFFF? I don't have this stock ROM, but that doesn't look right. I opened another similar ROM and it appears that there should be variables in there.

I am guessing he has overwritten ROM when he tried to do the 2byte stuff...

Ted - when you did the 2byte MOD did you use the big table (as above) or individual cells for MUT00/01?

Ted B

I used only the individual cells. I didn't touch the MUT table until you gave the values just above (which worked). In fact, I didn't even have the MUT table code in the XML until just before I posted the screen shot.

Thanks for the help Tephra. 2-byte load functions now. I have some ideas as to how all these things can be organized to make life easier for both developers and users.

I don't have a stock framed turbo (see my signature). If I did, this would be cake. Just recently, I tuned a different car with an EVO8 TME, exhaust, ported stock exhaust manifold, Brian Crower cams and 850cc injectors. I had the car switched from 93 octane to E85 in minutes, dialed in the LTFTs, then tuned it to give 300+ load, peaking at 29psi and holding 22 psi until 7500rpm - all with zero knock. This is all fine and dandy, but tuning my car presents entirely different challenges.

The WB appears to be working fine, but naturally, I will recheck. If it checks, this points to FP or a bad injector. FP at idle is correct, but I need a dyno to check it under load.


I wouldn't touch an AEM. Fortunately, there are other options. Nevertheless, dealing with the factory ECU is no picnic for the uninitiated. From square one, an individual could very easily invest the same (if not more) time in searching through thousands of posts for XML and hex adjustments as he would in tuning an AEM. The volume of material and time it takes to go through it increases daily.

u are running out of injector because ur running e85 it requires much more fuel

sabastian458

iTrader: (25)

he is running 880 injectors on a stock frame turbo. I seriously doubt that he is running out of fuel unless the FPR is starting to fail

I am running 850cc injectors and using 93 octane with a PT67R. A PT67R is larger than a stock-framed turbo (LOL). My fuel system uses dual Walbro 255 lph pumps. That is plenty good for the present setup. The only way there can be a fuel shortage is if there is a mechanical issue. Which while possible, is unlikely.

Ted before you do any more.

Please post the XML for the individual MUT cells.

I think you have overwritten REAL code which explains why the car is acting up...

you probably checked this already, but is your boost reference still attached to the FPR?
