i agree we, need a new quick start guide, something which gives a list of suggested settings for every single variable and an explanation of what each variable does would be really helpful. it's not uncommon for someone to upload a new version or something, get their old setup wiped out and have to start from scratch and maybe they'd miss something. a complete list to check with suggested settings would be very handy.

by the way, there's a lot of good info here, i'm learning a lot... keep it coming and thanks to turbobob for coming here and helping out.

I think that would be unrealistic since there are so many variables within each person's setup and any one thing could throw something else off. Also, it would tend to hold the writer somewhat responsible (not legally of course, but perhaps morally) when something doesn't work as expected.

My thought would be to explain exactly what each setting does and how it affects the outcome of the other parameters and maybe give examples.

A quick start guide is already available, however, it doesn't match some of the available settings of the most recent software upgrades. Therefore, this would need to be updated.

The terminology also needs to be put in layman's terms. Sure it is cool to talk "engine speak" when you are seasoned at these things, but some of us are still learning all the time. When someone tells me to "pull fuel", I have to question that. Can't we just say add/decrease, etc...

These threads are extremely important and helpful for all concerned running this system. It is an awesome tuning tool if you know how to use it. I will be the first to admit that perhaps I should have started with something a bit simpler but I'm not afraid of a challenge. I said I will get it to run, and I will.

I've said it before and I'll say it again....There should be a section on here for electronics. Widebands, stand alones, SAFC, SAFC-II, MAFT PRo, turbo timers, boost controllers, tuning, questions, troubleshooting, etc...where we could all go for the answers and experiences of other users. This would provide a one-stop place for us to go for assistance rather than dozens of threads and a 90 page info-mercial, spread out through several categories, forums and websites. Something like that, I believe, would put SupraMania, head and shoulders above the other white meat.

Well, I've gotten off on a tangent here so I will just shut up, but really guys, thanks for the help !!!

Sure I understand that.... but it would still be nice if someone could fill in all the blanks for a "stock" setup less the MAFT. Like 440 injectors, stock throttle body, stock turbo, etc... and a simple disclaimer stating to be careful and maybe an extra warning for certain variables that could really cause big problems if incorrect, and a nice explanation of what everyting is... that's all I want.... is that too much to ask? :) Maybe we could all come together and figure something like this out on our own and start a thread with our own Maft-Pro Quick Start Up Proceedure / Settings / Explanation of Variables and just have a mod edit it everytime there is a new version.

Exactly, that's what I've been trying to do.:naughty:

4.8 is an official release, not a beta (like 4.6x). documentation is being written for 4.80.

Good to hear. You probably don't hear this enough, but I think the forum appreciates everything you and Turbobob does for the MAFT PRO customers.

Yeah, the maft pro is just like my Supra, it's pissed me off, but I still love it. I'm glad you guys follow through on the improvements and support, it makes it worth every penny!

I've been using VE Table #2 and I see most people are using VE#1. I read somewhere that if your idle vacuum is around 20" then that is what I should be using (#2). I just wanted to confirm this since I am having the car tuned this weekend and wanted to clear up this question. What is the difference between those two maps???

you are correct, and basically the difference is at what RPM peak torque occurrs. With VE table #2 it happens at a lower RPM. This is typical of small cammed, turbo motors. Larger cams, less efficient intake manifolds, and stuff like that move the torque peak up and match VE table #1 better (like my GN).

So, should I be using the VE#1 instead??? I don't have any special cams.

NVM, I guess after re-reading your response, I should stay with VE#2.

From what I've seen on most dyno charts for MKIII's with aftermarket turbos, the peak torque is somewhere between 4800rpm and 5200rpm. This was observed on several cars running 61mm to 67mm wheels and pushing between 17psi to 24psi. so with that info and any other dyno info you might have for car, you should look for the VE table that has the highest numbers withing that rpm range if yours falls within those parameters.

peak torque at some constant boost...... with large turbos (especially on a dyno) you don't get full boost until the upper RPM's.

Better to look at a dyno sheet from a stock car, and make sure you are watching torque, not HP. (Dynojets don't count)

its not the turbo size that governs it, but more intake and camshaft.

for stock cams, I'd stay with VE table #2 for now.

Will do, thank you Bob. That one seemed to be the best for me up until this point.

In another MAFT Pro thread you (turbobob)told brn2drv to turn off the AFR and PT Tracking. Were you just asking him to do that to troubleshoot or should we have them both turned off all the time?

I already have PT Tracking off and that seemed to help my idle surging issue pretty well.

Should I also have AFR Tracking off??? If I do, won't that affect the AFR's through the ranges? Or if I am tracking alright, just leave it on.

I am just asking some questions since I want to have all the answers for tomorrow at the dyno in case the guys have questions or problems setting up the tuning.
