Yea, you're right, he has to lower it - I'm dyslexic as hell when it comes to LTFT's and which way to move the injector constant. :P

To get the LTFT's dialed in comlpetely, you have to play with...

You need to raise it more if you have posotive LTFT's. I think you should be on a wideband when you do it though. How high are they?

Vaccuum leaks can also cause this, so check for those too.

Ihave heard about the LS1/LS6 amf series that they like to have a few inches of straight pipe before and after to be consistent.

Remember, a MAF measures mass flow, and it is temperature...

I know they are not quite apples to apples, but I had a non-intercooled powerdyne on my LS1 for a while and I could only get the WOT timing up to 11 degrees at peak torque. It made 450 rwhp so I know...

Scan your map and TPS and see if there are any clues there. Those are the things that trigger PE mode. Otherwise, you are just SUPER lean so be careful. Do you have access to a wideband?

I have been trying to figure out my WOT timing on my 04 GTP since I got this package. It would never seem to add up to what was in the tables.

Someone on clubgp.com has recently posted that there...

I wasn't saying that as a slam against the software. It has all the things I care about (fuel, timing, etc.).

Any news oon getting the scan tool working a little better? I am heading to the M9...

I've been tuing with it for a few months on my 04. It is lacking a lot of the tables of the LS1, but it has all the important ones. I used it to tweak the trans a little and dial in some new...

I am not sure how much it would help unless you used a convertor box to scale it back to match the 2 bar output. Then you could rescale your Ve tables and run a 3 bar tune in speed density mode. IT's...

What did you do to increase your mileage? Did you change the stoich A/F to 15?

Just wondering.

-Geoff

I was looking at this table the other day, and wondered when it came into play. I was thinking that I should just copy my high octane table over to it, just to simplify things.

This is an 04 GTP,...

Sweet! ;D

-Geoff

I've tried it a couple times and didn't notice anything change. It looked like a number flashed in the table view for a second, but then the LTFT's jumped back to where they were.

I am having more...

I dynoed today and I can verify that there is no COT in the PCM, it must be built into the PE tables.

-Geoff

Maybe the question should be - do the 04 GTP's have a COT function or is it built into the PE adder vs time tables. That whole section is way different than the f-bodies, so maybe they handle it a...

HpTuners will work through a USB --> Serial converter, won't it?

-Geoff

I am pretty impressed with the software thus far. The only thing I noticed was that the COT function is not changeable right now. The box around it says COT enabled, but neither button is switched...

... specifically the '04 Supercharged SS? I am in between an '04 GTP and one of these and tuning software is a prime consideration. I know you support the GTP but I need to ask about the SS before...
