numbers...


In case you cannot read that small azz print:
159 hp
165 tq
AFR goes 10:1 as soon as he hits WOT
Second run is:
153 hp
164 tq


Long story short:

The TPS on the SVT is different from the Standard duratec. Additionally the PCM believes that WOT would occur at 500 counts under stock calibration on a standard duratec PCM. The SVT TPS and PCM like to engage WOT at about 1000 counts.

Anywho...The reason I was running 10:1 AFR at WOT was because the PCM was very confused. This problem has been remedied, but I still have not dyno'd since SZ06.

What numbers to I expect...idk.

My commanded AFR is about 12.5:1 right now. According to my AEM wideband all is well.

I hope to dyno again soon and show some better numbers.



The car is not slow by any means and it isn't a hack. I have embarrased a few cars that thought I would be an easy win. I will dyno again soon, but only after I have done some more street tuning.

if you were running the svt tps and stock pcm, i could have told ya that.

hope it runs a lot better now Pete. Guess we'll see what it makes at SZ 07.

well I have SVT throttle body and a stock SE PCM, my car seems to be running fine, the A/F is the best it has ever been

Is this issue because of the tuning that you have been doing?

if you have the SVT throttle body, you have to use the SVT TPS.

Max TPS counts is like 1024, but WOT on my SVT was around 750 counts and I saw no need to change it.

Just FYI in case you want to check it. I think 1000 is too high.
Damn, that AFR is in the dumps, I bet it was actually below 10:1 as a lot of widebands don't even register much below that.
lol Hows the gas mileage?
Hey, did those stock SVT timing tables help out?

yup I know that I have a SVT TPS, what I was asking was if the issue came from his tuning because my car seems fine on a stock SE, untuned pcm. ultimately what I am getting at it will I have the same issue when I go to get my car tuned?

Yeah, mine is set at 900. The stock was set at 500, once I changed this ONE thing my AFR cleaned up and the car is fantastic now.

Brapple, I think it has something to do with my PCM. I have processor code KKT4 with traction control. To be honest I am not certain why this was an issue with my PCM and not others, but it was an issue nonetheless.

I would like to thank Derek for point me in this direction. Actually at the banquette.



Yeah I wanna say it was DEF below 10:1. His wideband only went to 10:1, but if you look at the misfiring...well ya.



Oh and yes tom the timing tables helped out A LOT!!
