EFI Live and HP tuners in same PCM? Can you use both simultaneously for one PCM?
Got dyno tuned with EFI Live and its spot on, except for the idle. Went and got the idle tuned with HP tuners due to the tuner not being able to get the idle right with EFI Live, something about EFI Live doesn't have some tables that HP tuners does. I have EFI Live, which is why we tuned it with it, in case I wanted to make little changes to the tune without going back to the tuner. So now I can't load the EFI Live tune back into the PCM without buying another license for some reason. The vehicle developed a power steering leak, whats why we didn't finish the tune. Anyone heard of idle issues with EFI Live? How can I reload the dyno tune without buying another license?

Yes, used my EFI Live as my tuner didn't have the hardware. I just had him download the software to get familiar with it, I brought my flashscan down and we used a license I purchased on my laptop. The tuner stated something about a dead spot in the fuel tables?
It idles great with the Hp tuners tune in it now, I just can go past 20% throttle without the possibility of damage to the motor. I have no idea how to tune otherwise I'd look into using EFI Live more.

It has a HP tuners tune in it now, is that making it interfere? Does it matter if we switch to a COS? I don't remember what OS the PCM had when we licensed it, does it matter?

If you used an HPTuners custom operating system, EFILive will not read it - and vice versa... custom operating systems are proprietary to each company and must use that company's software for tuning from that point on...

Alright, does the HP tuners hardware have to be the same one used, or can another one do it. The one that was used is a unlimited license one or whatever, but its 50 miles away. My buddy has one, if I could use his, that would be easier.

EFI is not the problem. The tune is the problem. If you licensed the pcm with your EFI cable you can flash it as many times as you want for free. It doesnt matter if 5 people with HPT flashes it you can always flash it with EFI for free. If your friend doesnt have unlimted license for his HPT cable it will cost him a $99 license to flash it with his HPT cable.

You need to do the same thing I did. I had a pcm tuned with HPtuners but I own EFI live. Therefore I could not tune the car myself and its a 3 hr drive round trip. I purchased a second pcm. Same one 0411 and just installed an EFI live tune on it. It took us a while but we were able to get the car to drive and idle with both HP tuners and EFI live and I use 160lb injectors that are low impedence with resistors. No driver box.
I took the pcm that runs good, the one that has hptuners on it and mounted it in my trunk. This way if I ever have a problem with the pcm that I am trying to tune I can just get my back up and still get the car home. That is what I would do. Get another pcm.
