So I was using old tunes files from comparable builds. I started from scratch with a new written OS and so far no problems. Only one car so far though.

Let me start by saying I'm not the best tuner the planet has ever seen, but I have tuned well over 1,000 cammed C5's in the last 20+ years. In the last 6 months to a year I can no longer tune a 411...

I had a customer tell me his was still on too and I used HP on that car, I checked the file and it was off but I have not seen the car back yet. (since EFI Live doesn't sell the stream...

Update. I rescaled it back to 312.500, normally in the E38 this sensor has an offset of -11.25.

In the E92 to get it correct I had to set the offset to -1.8, I am at sea level so I brought the...

Thanks Ross, I spoke to Jesse he gave me suggestions to correct the offset.

Thanks for your time. I'll post my results once I have it dialed for others.

Hi guys, I am using a ZR1 MAP sensor for a boosted C7, if I scale it to the normal 312.5 it's way off.

If I scale it to 500 it is at 100 KPA KOEO, but it still isn't scaled correctly. I can drive...

Hi guys,
I have a 2012 Grand Sport Vette that runs/idles great with the traction control off but as soon as I turn it on the timing drops to zero and it runs like crap.

I have lowered idle way...

Just to give the answer to this, it's starts with me over looking the obvious... (as usual in these situations)

This car oddly just locked me out of the ECM a while back, never figured that one...

Im going to pull it in HP and take a look. If that doesnt do it I'll forward the tune over to you if you wouldnt mind?

Thanks for responding Howard,
I did a quick even percentage drop of both the VE and IFR tables to see if that would make the pcm think it was producing less TQ. I would not leave it that way, I...

I have tuned a bunch of high HP A6's, but I think they were all older models maybe. This 09 will have a perfect graph going on, and hit a brick wall at 680 rwtq. It will shut the fuel off (pressures...

Hi,
I noticed that the ZR1 map sensor is listed as a 2.5 bar sensor, but if you look at the scaling in a stock ZR1 tune file, it is scaled at 312.500.

I have used it in other applications, and...

Fantastic! ordered, Thank you sir. :cheers:

Hi,
I just received a new LM2 from innovative Motorsports. I previously used the LM1 and had it go from the LM1 with a gender bender to the V2 for a serial port connection. (phone jack...

Your lucky, I was personally very dissapointed with the class. Someone needs to let people know that "EFI" university has nothing directly to do with "EFI LIVE" tuning software. I think it can be a...

I will do some dyno testing as well, thanks for posting your results. :cheers:

I had an issue with a rev limiter kicking in at 6600 rpm, even though my limiter was set at 7000 rpm. After logging a ton of things to try and figure it out, I did two things at once that fixed it...

I do the same, but leave them in closed loop for fuel economy.:)

I have had problems in the past with Jesel valve trains being heavy. It would cause an intermittent valve float that I guess was off of harmonics of some sort. Try swapping out the rockers, it has...

Beat me to it, I did that too a while back. I found that just leaving those tables alone (besides shuting off upshift TQM to "no") does not effect power at all. So far anyway.

Update;

I got everything working with the factory/EFI live two step and brought it to the track. What I found was that I actually got slower 60' times then just foot braking!

It seemed that the...

Boosted, and I will be logging. I'll keep you posted, thanks for the help guys. :)

Thank you sir! :cheers:

I'll try it for a while and post up the results when I have had a multitude of passes with it.

I was going to go into the rev limit type section and switch it there. I assumed that would do it? Either way though, I only planned on sitting on the two step for a second +- for pro tree index...

Thanks,
I was thinking of just getting it working, then change the rev limiter to spark instead of fuel. Opinions?
