That sucks. I guess I assumed that you would know where they were. I'm currently running an Aeromotive A1000 regulator, which 1:1 vac/boost referenced. What regulator would you recommend Chris?

Hi, I've built a car to make some healthy power. It has 95 lb injectors. The problem I see at idle is that the injectors are large enough, that my PCM can't command a short enough IPW. As a result...

Rick,

A couple of years ago when I first put on the MP112 with LS1 MAF, the car ran crazy lean with the stock MAF tables. It cruised at 18:1! It calmed down as soon as the correct MAF table for...

It was very easy. Just put the new MAF into your intake tract and code in the new MAF table into the PCM.

John

I'm sorry Rob, I'm not following you. ??? The injector skew table entries are multipliers for the injector pulse widths. If you want one injector to have 2.5% more fuel than the others, you set the...

Excellent question, I was wondering that myself.



Rob, why wouldn't you just put a 1.02 in the appropriate entry? What do you have in mind?

John

Probably not. It would end up running lean. I would hold of on adding the new MAF until you or someone else was ready to input the new MAF airflow table.

John

Many people run LS1 MAFs. I've been running one for almost three years now. One of the nice things is that they can flow more air before hitting our PCMs' 11,500 Hz limit. If you change the MAF...

SD operation. Or am I thinking of SD with a 3 bar MAP... (I have a GTP)

John

I thought this was not available on the V6 yet. You must be beta testing a beta version? Or am I missing something?

John

John,

I am embarrased. I thought I had gotten back to you. :banghead: Sorry dude!

What's happening is that when your car goes into TCS mode it looks up the AFR and goes lean. Go to...

The point at which your injectors go static is a function of RPMs. At lower RPMs you have more time to get fuel into the motor (and less likely to go static) than at high RPMs. The point at which...

Hi, this is a question for HP Tuners since they're familiar with the OS portion of the PCM code and what basis some decisions are made on...

If I look at the V8's, There is a PE Enable %TPS vs RPM...

Ken, you mean that histograms only work for pre-defined units? Any plans to add FJO?

John

Dirk,

The table you posted is non-zero only between 0.8 and 2.5V. Are you sure you're using the right range?

John

Yes, I see what you mean. I scanned at the track today and noticed the extra lines in the table display. I didn't play with them yet, but I'm sure it'll be fine now.

Thanks,
John

Is there any way for me to configure my scanner table for the aux inputs and outputs and then configure those inputs without actually being connected to car? I was told that I had to be. The problem...

Yea, we just get better results naturally. ;)

....especially if we're FWD ;D

John

Found it. Thanks!

Hey, these guys are TOP NOTCH! I'm racing this weekend and didn't want to be left without an interface for scanning purposes. They rushed out my EIO to me. Woohoo, thanks fellas!

When I first...

Dirk,

The mapping under the 0 - 5V column fits the formula AFR = (V/.5)+10.

John

Keith, what's the formula for the FJO unit?

Whoa, wait a minute. Ken emailed me that there was native support for the FJO, Dynojet, and LM1. Am I confused? Which ones are pre-defined?

John

It is my understanding that different brands of WB O2 sensor/controllers have slightly different transfer functions or curves between the analog 5V and the reported AFR. When V1.5 becomes available,...

Yes, there's a whole bunch of us taking small steps. I usually change one or two things at a time. I'm very happy with the results so far.

You probably won't see too many of us posting on ClubGp,...
