SCT has their racer package software for $350.00, would still need a flash device and a laptop.

It is common and can be found all over the net.

Just log MAF and RPM and you can get many points. Pop those points into excel and you get can get a graph of HP. To get torque you use TQ(ft-lbs)=HP*5252/RPM. Right now all I have is an OBD scanner taking logs of the car.

This is the software package I am looking at right now:http://www.hptuners.com/order.php
It is $499 to tune 2 cars.

Our tuners allow us some basic adjustments... spark, timing... but the fuel mapping and other stuff is basically hands-off.

This is what use to tune subarus:http://www.romraider.com/
It is open source and the cost to start was buy an $80 cable to tune an unlimited number of cars. It is a shame it won't work on the fords.

You can estimate the CHP with this formula: 1.31*Gm/sec=CHP, of course this depends on how accurate your MAF scaling is. My stock '05 comes out to 305CHP.
Ohh I have another question. Why is there not more people tuning thier own car? I come from a subaru and there are a ton of people tuning the cars on thier own. I have been tuning for years and I am amazed that there is not more mustang owners doing thier own tuning.

I still have to question how good these "estimations" are with these formulas. I would actually put my money on the dyno being more correct than these formulas. And to be honest, I don't really care too much what kind of numbers my car puts down. What matters is what it runs at the track!

AWD sure is helpful, isn't it??? So why did you buy a mustang GT again?
(Just a joke man... that's a really nice time. STI I presume?)

Quite honestly, I do not feel comfortable messing with the tune on my car. I would rather pay a small price for a tune that is tried and tested by an expert rather than start "trying out new things" that I saw somebody else do on the internet. Just my opinion.

Looks like you have some ground to make up to get back to the level of your Subaru. Get to modding that thing!

I did that without even trying. Actually a lot of people run mid 12's with just bolt ons.


What is 233gm? Is that the same as MAF counts?

This gauge records MAF counts and lbs. per minute. It also records crank horsepower, probably using a similar formula.




I have free software to tune my motorcycle. Even if there was free software to tune my mustang, I wouldn't do it. There really isn't much need for it, like someone else said.
