---===The Official MAFT-Pro Thread===---

I've been out of town for a week or so.

The next version (Beck and Rustangs stuff) will be posted in a day or so. Its done, I just need to tie up the loose ends.

Then we can get back to fixing stuff...

If you are getting an airflow CEL, it will most likely be the wiring connections from the green wire (10 pin harness) to the ECU MAF input.

Check with a logger to see if the MAF Hz match the FO reading on the pro.

Sometimes if I let the car sit for an hour after driving it, it doesn't want to start and stay running for a few seconds, I have to hold it at 3000 RPMs until it stops missing. What setting do I adjust for that?

Also, my TPS sensor wanders, so that causes a lot of problems. Everytime I re-adjust it, viola, the car runs like stock again (except for some decel issues which are to be expected). I have a new ISC on the way and this should add mine to the running like stock list.

What's the quarter mile record on this setup. I'm going to the track next week and I want to see if I can break it. (crossing my fingers it's not too deep into the 11's).

[TurboBob]

what is your afterstart set to?

Check that your thruttle cable is not too tight. Throttle shaft bushings and seals can affect how well the throttle closes and the tps reading.

I think Rustang has the hp record for the 3S guys.

Afterstart 15.0

The throttle cable is fine. I'll just wait to see if the rebuilt ISC fixes it.


There arn't any AWD dynos around here yet. Sooooo, I'll just have to report my quarter mile time and we can estimate.

ok well good luck with the track.. are u using race gas? and lots of boost? anywho good luck run some good times so i have something to shoot for over summertime.

[runner4053]

Race gas and 21 psi boost.

[Rustang Cobra]

i guess i have the record because im one of the few to dyno with the maftpro

are you sure you guys need aftersart enrichment??

ive never used it on my car or on my friends that i tuned and both of ours start, run and drive great. I never having stalling issues, it never takes longer to start after sitting, its just perfect really.

i want everyone thats using afterstart enrichment to set it back to 0 for a couple days to see if it makes a difference

I made 400 awhp on pump gas and 16psi so I guess Rustang has made a little more than I did.

I just wanted to tell everyone that I was having all sorts of issues and I finally went and took out all the quick connects and soildered everything and my car is running beautiful now. It is almost as good as stock. I have some more work to do with the VE table but so far things are working well after being soildered ( I had already soildered the TPS). I HIGHLY recommend you solder your connections before you go any further with tuning.

I was having some wierd issues with my car not behaving as it should with fuel trims. I have 680s and had to have my fuel set to only -25 and I was adding in almost 15% at idle so I had a User Tune of only -10 when it should be -45ish which is where it is now. I am very happy with things right now. Car is pretty fast.

yea my summer project is to solder all wires and hope timing is around the corner . nice dyno numbers btw

any updates on the latest version?

[TurboBob]

4.6 is done, just putting the wraps on it.

I will post it here first...... probably tonight if I can get to it.

The quick-connects work well most of the time. They need to be installed firmly. that said, they are included with the kit for convenience, and soldering the connections is the best way to be really sure things are connected well.
