I know I am already behind the power curve. I am not running a WB02 as of yet. I just don't have the time to get it done. Here is the scenerio. I run a 355 TPIS & 58BBS T/B with 42# injectors Vortech S/C @ 8lb boost I swapped from the 165 ECM to a 749 ecm and have finally been able to get my Snapon MT-2500 to read most of the data while running. Using Datamaster I can't get it to work at all. While the car is running I have watched the O2 MV and was told at WOT I should see around 950.. Is this correct? Next question I have might be a faily important clue to me as to what is happening. I have watched the BLM's and the Integrator. BLM's are real close to 124 so I know it is a little rich. But the integrator almost immediately drops to 80 and stays there. I have been told that the TPIS likes it fuel. I am thinking that the car is really rich and it stumbles when accelerating almost to the point where the car has actually died on a punch before. I was told to add AE but I think this might be to rich now. I know to adjust the F29c close throttle then F29 before adjusting boost fuel... Can I use the integrator to help with this fuel problem.

Integrator at 80 = bad.

Many who say BLMs are good but integrator is bad are missing the whole point of BLM. BLM is an attempt to keep integrator at 128. If BLM is good, and Integrator is bad, then BLM just hasn't had enough time to learn, or BLM is not enabled, or the BLM limits are set to clamp BLMs at a "good" number.

Integrator shows how hard the ECU is trying to get to stoich. If integrator is not at or very near 128, then the BLM will try to adapt in order to get integrator back to 128.

If Integrator has to work too hard to get stoich, drivability will suffer greatly. Possibly stalling, as in your case.

The only way to get integrator and BLMs to both look good is with VE (and some transients) calibration.

Use VE to fix the problem. Use integrator to see which way and how far to change VE.

Get VE for normal driving squared away before going into boost.

Ok I followed your advise.. I was able to get my VE tables in somewhat better order. I was able to get Tables F29C (closed throttle)

With the Integrator between 125-130 The BLM'S are trying to stay between 125-127. Just a shade rich.

With the RPM between 800 & 850 and Map KPA between 30&40 I have 18.8 & 21.9 as my new respective numbers. Which is considerably lower than what I would have thought the TPIS miniram would have needed over TPI.
Originally the numbers were 34.4 and 37.5. I dropped the numbers all the way through-out the scales with C.A.T.S. and not TP so it would be an even drop.

When you accelerate in park now the car doesn't stumble like it did.

Now from what I gather is to get F29 VE~RPM~MAP in order.

Question is. I am not using a WB02 and I am running a Snap-on MT2500 which I know isn't the ideal situation. What is the best way to tune F29 now. I am guessing with car in Drive, Brake engaged. Since it is not considered close throttle. Please correct me if I am wrong?

Currently testing that way that I just described.. The Integrator is staying around 122 but the BLM's are staying between 116-118. But it is occasionally stalling. Should I try to get these both as close to 128 as possible?

Then I know after that comes the Adjust for Boost.. Then it will be fun.

If you do a lot of driving, you can just drive to get the main VE table in order. Data log all the driving, and see how much correction Int and BLM are making, and then apply that to the VE (in a smooth manner). Repeat and repeat and repeat. Try to get it all within the 122-128 range. You can use the breaks a little to try to hold a specific RPM and Load, but don't cook them too much. Can use that to also get the low RPM stuff a little closer, too.

I was advised to get F29C closed blade throttle right 1st. I think I went a little to far with them. I am using the Snap-on scanner. That is the only way to see what the BLM's & INT's are doing. Says the car isn't learning AFR for quite some time. The BLM's are staying at 128 but the INT is going to 160 unless I step on throttle. I know that is lean.

Should I try to get F29c in order like I had it once before with INT's in between 126-130?

Should I adjust f29 after AFR is learned?

I don't use $58, so I don't know the consequences (if there's something special in the software) of doing them "out of order" but generally, you should try to get the idle right, I guess.

F29 can be tuned by using the learning of the ECU. If you see that it is learning UP in a particular area or general region, then bring F29 VE up in that region, and re-test to see if that brings the learning down to normal. Repeat everywhere that's reasonably possible. Then, tackle boost.
