You can wire a consult to your T/x R/x wires and down load his tune right from your car and save the bin file for use in tuner-pro. Once you have the tune you can modify it's parameters and burn a new chip.....I use his SR tune for my car, 740cc injectors, 2871r, z32 maf etc.. runs 14.5 at idle 11.8 at WOT 25psi no issues at all

I'm still running one of his tunes. It's not the most efficient, but it works.

The only thing I don't agree with, is he sold me a tune that he pulled off the internet. Since I bought my daughterboard, and even paid for another tune from him, I have learned alot about tuning.

I'm not going to bash him anymore. You can read around and make your own decision. I had a good first experience, but it slowly went down hill. Since then, I have learned how to tune myself. I'm just glad my motor didn't blow up.

On KA24DE's and SR20DE's, maybe a few other ECU's, there are two parts that the ECU looks at for information.The first part is the stock 'chip'. I have no idea where it's at, or what it looks like.The second part is the 40 pin header that has nothing attached to it. This is where you solder a connector that allows you to plug in a circuit board. You then plug chips into that circuit board, or 'daughter board'.

When you solder in the daughterboard with the chips, you must de-solder, and re-solder a jumper on the ECU to tell the ECU to stop looking at the stock tune, and to now look at your new tune on the daughterboard.

The chips you plug into the daughterboard, are burned with the many types of burners out there. Mine and a few others, use the Willem burner for the SST27SF512 chips. You load the 'tune' into the burner software, and burn the chips. You then plug the chips into the daughterboard in the ECU.

Your 'tune' that you burn into the chips, is modifiable by Tuner Pro RT. That's what I use personally. You open the tune in Tuner pro, modify it, then save it. Put it into the willem burner, and burn your chips. Then plug the chips into your ECU.

This way is very time consuming, and is not modifiable 'on the fly'. You cannot hook a USB or anything into your ECU to let you modify the tune. The only thing you can do, is datalog with a consult cable.

I'm at work trying to describe this as well as I can, as fast as I can. Dig around on the net about tuning. It's a little confusing, but can be understood after a little bit of reading. AIM me at EazyE4You if you wanna chat about it.And there are a few people out there to make the daughterboards. You can pick up any daughterboard, get the matching chips, and a burner to burn the chips and you are in business. Tuning, or modifying the 'tune' is a whole nother egg.

Where could I get all the necessary things to tune?Like the burner, header, daughter board, and what kind?Are you still using the daughter board Jason sent you? Or are you using something different?I'm wanting to go ka24de-t just to let you know what I would be tuning for.

Like if I buy this it can burn SST27SF512 chips.I know this is just one part I also found the SST27SF512 chips for a five pack for $15. What chip does the E-Mance tune come with?http://images.google.com/imgre...m%3D1
