Any plans to support the common rail 5.9 cummins in the near future?

If you pull timing and the knock does not drop that means there is external noise triggering the sensor. Check for worn mounts ect. Also swap on some stock coil packs. MSD coils and junk and are know...

This is how I tune my gp.

You have a pre cat and post cat for each cylinder bank. It will only use input from the first sensor in each bank to adjust fueling. It will do that in clsd loop. they are 0-1v sensors 0 lean and 1...

Hmm, that worked, why did it not work when I typed it in? I am 110% sure I typed it in right.

I just purchased 2 more credits for my interface today. Got my new key via email and am now trying to update my interface. I type in the key correctly and it says its invalid. Is there something I am...

You just need the 04+ throttle body, might as well get a gen v charger and tb combo.

You can swap in a 2005 pcm and tune with that.

I guess I have never maf tuned that high in the hz range. I will have to try this tomorrow and see what I get for results.

here is my last tune :banghead:

The knock comes in in secound I can try messing with my timing tables tomorrow to see if it helps. I had my a/f at 11.3-.6. Then when It was still knocking I tried adding some fuel to see if it would...

Here is my config.

Yeah I had a poor 60' time. I have done a maff tune and my fuel trims have been locking in at 0. I dont log 02 mv because I use a wideband. I guess It would matter on the config you are using to look...

Went to the track last night. My pb was 14.1 He is a scan of my last run. I had been adding fuel over the night to try and kill the knock, but that did not help. Any help is greatly appreciated. I...

I will be flashing a gt this weekend and need a good file. I am not driving it, he just wants a canned tuned. I would make one my self, but I am not sure for the trans shift points, how do I detrimin...

I have the NGK AFX, but it does have both. You need to use the with power to it. If you have a multimeter you can see which one has the 5 volt signal.

I got it dialed in now. Running mid 11's for afr.

How many miligrams/sec would you recomend then to change each time. Right now I am in the low to mid 10's and need to bump it up to 11.5-11.7

They are real close It is kinda hard to tell since it is always changing, but I think it is right on or maybe a milisec behind the afx read out

What is the best way to add and remove fuel under WOT using the PE table or scaling the maf? I have a wideband.

I didn't take any when I did it. I couldn't find my camera lol.

This is a write up to wire a NGK AFX Wide band to your hptuner with out the inputs on the tuner by using the egr circuit for grand prix. Wire color could vary model to model, but it is basically the...

I would think you would just have to add some fuel. The larger bore will let more air in so you will need more fuel. That is how i see it.

I have a 2001 Grand Prix GTP with ss autochrome headers. I have an 02 bung right before the flange to connect to the resonator. Since I do not run a cat would I be able to place my wide band sensor...

Thanks
