Do you have air injection hooked up? This will send air into the header before the O2. If one side is blocked and the other is faulty or gets all the air then the O2 will read free air on one side...

Hay Howie,

yah it was opening to a right angle -----

Thanks it worked perfectly.

I have a lecture to give on the 20th, next time.

Well, I am trying to figure out if my throttle blade is opening all the way at WOT. Reason is this. My tuner thinks that the BBK is not opening all the way at WOT but the stock TB is. This is with...

Thanks will look more closely at TPS vs MAP.

Also though, is there an issue with the MAP enable being higher than stock 15 and hyst 6?

You do need to have PE at part throttle none boost as well...

I have a 427 with a procharger P1 putting out about 8# at 6500rpms. There is some boost pressure as low as 2000 rpm though on the 427 its likely not going to show as boost(that was with the same...

Min Spark advance table vs rpm in the spark control spark retard area, what does it do. I am a little confused. Is it the max spark retard allowed for a given rpm or is it the min. timing that is...

I agree, mine is extremely similar to soundengineer's. If i put the PE enable TPS below 33% above 5000rpm it will flood the engine when rev'ng at low MAPs 20-40 kps. I have tried to compensate for...

Does anyone have the values of a LS7 base spark table and/or 9:1 compression 427 base timing table. I am just curious to see the values. If giving a none ls7 table please specify cam, thanks.

Thank's for the link. I may do two wide bands with emulation of the narrow band o2.




Up date on tune issues. Misfire in the 2nd cylinder see by checking exhaust temps. That was dumping raw...

Thanks for the replies so far. I will try the table mod for the open loop warm AFR.

Sidestep let me know if your plan works.

I am also going to put a thermal blanket on the headers to...

I have recently installed long tube headers and at idle(closed loop) my wide band reads 13.6 AFR when command AFR 14.6. No codes from o2 and there seems to be normal variation in the O2 signal. It...

Logged data show shift is being commanded later in 2nd gear to 3rd gear when luck is enabled during shift. Why??? Can this be changed?

I have an A4 98 level V trans with 3.42 3400 stall. I recently moved from ls1edit to Hpt. When i did I changed my TCC to lock on shift which i thought i had done on ls1edit but when i did the first...

Thanks.

The last question regarding hooking up a TCC lock switch. I believe all that is needed is a switch to ground but which connector position needs to be grounded?( on the PCM)

I realize that 3rd can be held for a dyno run, but i am confused about keeping the TCC lockup during WOT. What values do you place in what table leads to this?

Also how do you hook up an external...

No not the COT.

Maximum allowed enrichment expressed as 1.13 stock ecu. On a procharger supplied tune 1.24.

I have a supercharger on my LS1 5.7L Corvette CR 10:1 Boost at 6-7lbs to 6500rpm. I have the PE table set up on a dyno for 11.7AFR and Adv to 16 degrees. But on the street i had to drop the advance...
