For those who are using the programmable outputs, where did you purchase 200ma inline fuses? I've not had any luck finding any.

Bill, that is correct the COT was not disabled. I logged the CAT Temps the day after I had made the previous log and both never exceeded 1485F during the 2nd gear pulls. Looking at the COT...

This is also something I've been working thru in the tune on my 07 Trailblazer SS learning the new os. It was my understanding that the Open Loop target afr is calculated based on the OL Gas (gear),...

Update: Reinstalled the software and now the fuel trims are resetting using VCM control in the scanner.

As for the knock learn factor, it looks like the #s mean different things with the LS2 os...

Thanks for the feedback guys. I've been tuning with the high and low octane tables the same and understand that there isn't a reset button for the knock learn factor. I was just trying to figure...

I just purchased an 07 TB SS and started playing with the tune earlier in the week. First log the knock learn factor was at 0.11 and the engine was picking up some kr. Turns out the dealer filled...

On Greg's 07 F150 there were no KR PIDS to log with the scanner.

Russ, thanks for the tip. That addressed the idle issue with the stock map. With the stock map, stock os, stock inj, no maf, idles great.

I reinstalled the 3 bar os with the stock injectors,...

I originally was running 3 bar with 96 lb/hr injectors when the problem was first found. I had 350 miles on the 3 bar tune with the turbo with no problems. A couple weeks ago I began expereincing...

No, the fuel pressure input wasn't hooked up the MPVIPro. It's steady @ 40 psi. One thing that is interesting is that the IAT and STFTs are dropping out during logging (I was using the record...

Thanks Bill! I forgot how a low MAF reading from it being unplugged will skew the logged dynamic cylinder air. :doh:

I'm still stumped as to why it goes lean in SD.

A few weeks ago I ran into an issue with my turbo setup on my 01 TA with a 3 bar tune. I have 330 miles on the new turbo setup and the car was running great, tune was finished. Suddently the car...

I downloaded the tune and info file for a buddies now 07 F150. Bill, you have mail. I'd be more than happy to evaluate any beta software that might be available.

I was still seeing very low dynamic airflow #s even after I deleted the MAF. I ended up going back and recoverting my na tune with the stock os to the 3 bar os and rewrote the ecm. Everthing is...

I just started a 3 Bar tune my 01 TA (402, 232/228 115) after installing a turbo kit. I'm running 83 lb/hr injectors with 40 psi fuel pressure at idle (boost ref fpr).

I'm having the usual...

Thanks for the info. I received a Belkin USB cable with my MPVI Pro.

I used a different USB and OBDII cable from another MPVI Pro interface to check if the cables might be the problem. Still had the same issue.

The past two days I've began having issues with my MPVI Pro interface. I've had my MPVI Pro for a few months and had no issues until now. I am getting an "interface was not found or is not...

I'm getting U1000, U1016, U1040, U1096. At first I thought those codes were setting my SES light, but it turns out I had a P0300 lost in the middle of all the other error codes.

I'm in the process of installing a 402 LS2 in my 01 WS6. I'm going to be reusing the stock LS1 knock sensors mounted on the sides of the LS2 block. I'm curious is anyone has an example of what...
