Ok thanks.

Maybe I'm not fully understanding this but by multiplying the KR decay by 2 aren't you actually adding time until the KR is dropped and the advance is brought back on?

So should you raise your shift RPMs and speed at an equal percentage. Would that work out?

Thats what I figured. Thanks

I have a quick question about changing the max shift RPM. I noticed that there are 2 tables, 1 with shift vs speed and one with shift vs RPM. I assume that the 2 tables are used together and must...

Go throught russ's open loop maf tuning, the write up is great. It tells you where all the tables should be at the end of the tuning.

There is not set amount of timing advance that you can add to the table, you have to do various logs/scans and add/remove timing where it permits. You cant just "add 6 degrees of timing" to the...

Hey guys, I just completed my maf tune tonight, and I thought it seemed really good, 0 LTFT @ WOT, and AFR seems good, although a little rich.

I noticed however, that on initial throttle tip-in...

So I have to jump up to a standard GM 2 bar MAP, ok. Is there any programming to adapt a 2 bar to my set-up?

I have a 2004 3.4L v6. The MAP sensor is a stock sensor, which I believe is a 1 bar map correct? Is there any way to log boost? I've tried a couple times with no results.

Yeah, the nozzle it came with was 9lb/hr, and you could feel the car bog when it came on, more than likely flooding out the spark. I have done the calculations and for the approx power output and...

So where you spraying into the blower with the alcohol? Is that OK for the rotors? What size injector did you use? Im going with a 4gph. Looking at my best run to date, the scan showed my IAT...

Could that contribute to a slight delay on tip in? How do I tune those individual cells?

OK, thanks ill try this again.

I must be doing something wrong but I am getting better. My LTFT locks at -3.0 @ WOT.

My question is from this quote. It is the 3rd paragraph down: Then copy & paste the Maf error % histogram...

Looking back, I think you guys are not understanding what Im talking about here. I am talking about a water (meth) injection system, not placing my IAT after my fuel injectors.

The alcohol injection is in place to cool the intake charge in addition to raise the resistance to knock when in boost. The way I see it, with the IAT at the outlet of the blower before the...

I don't know how many people have any experience with alcohol injection, but I am thinking of relocating the IAT to a port on the upper intake manifold about 6-8" after the injection nozzle. Will...

OK, I am going to chime in here. Are you saying that if the add vs tps table is zeroed, so should the add vs RPM table? Maybe this could be the reason I am not hitting my target 11.5 AFR during WOT.

Oh no, when I took that scan, I was not logging the commanded AFR. This time when I try the histogram I will make sure the commanded AFR, actual AFR and the MAF hz pid's are in the table, then it...

Yes I know that but even with the maf hz and the maf error pid in the table, the histogram is still not working. Ill get another scan tonight with everything in the primary table and add the...

Oh, sorry. Here is my scan. I noticed however that in this particualr scan, that the maf hz is not logging. Not exactly sure why, because it was working on the graph before, that wasn't my issue....

I am having a problem that I have never had before. I have done a maf tune before, and I wanted to do another one tonight to try and dial it in better.

When I try to log a histogram of the MAF...

Im working on my MAF tune right now, granted I am using an LS1 MAF on my GA, but from what I have found it that the 3400 is best tuned for MAF using the method from "Russes OL MAF tuning" for the...

OK, so I found out that the system fuel pressure is 58PSI. So going by the graph, I have come up with this:

Injector rated fuel pressure: 44.3 psi
Fuel rail pressure: 58 psi
Injector flow...
