Looks like a lot of the sprint car guys in my area are starting to get into the LS series stuff. There are iron block LS series popping up, and the LS platform is the natural progression to the gen 1 based platform engines that everyone is running

I am currently running into guys who are wanting to build budget LS for these series but don't know much about EFI or standalones or any of the likes since they come from the world of magnetos and mechanical fuel injection. I'm trying my best to steer them into the more known standalone routes like Holley, Haltech, or even factory PCM. Hence this thread

I know something like 40% of the people on here are on Holley, and another 40% are probably on factory PCM

Is anyone running a straight methanol car as the sole fuel on a factory PCM? Not sure if that's within the scope of HP Tuners

Also if anyone is running a weird ECU or something lesser known/talked about here like Link, Fueltech, Syvecs, Motec etc. I'd enjoy to hear your thoughts on it

 

With a gen3 P59 PCM, you can set stoich anywhere from 1/1 up to 26/1, and put in fuel injectors up to 254lb/hr, so that should cover methanol. Up to 8000rpm is not an issue, but after that you max out spark control and airflow tables. They can be tuned with free software via pcmhammer and tunerpro with the use of a very inexpensive obdlink cable. Standalones are nice for the features and tuning simplicity, but add in a lot of extra cost.

 

That is exactly the information I was looking for. Going to assume gen 3 PCM with HP tuners is something more tuners would be able to work with.

Thank you for the insight

 

With the Haltech Rebel LS controller being available now it's really hard to recommend going another route on most common setups. It's a great ECU that is reasonably priced and you get real motorsport grade features with real safeties and I can't think of another computer that could compete with it for the price. As far as running Methanol you would want to step up to an S3/R3 to run the wideband compatible with NTK sensors as I don't believe the Rebel can run anything other than the LSU 4.9, but I don't know that for sure.

I would not recommend a stock PCM for a race application swap, you are missing out on a LOT of great features. If it were a plain old street car with hardly anything done the factory PCM certainly has it's place for swap applications.

Not a fan of Holley computers due to hardware issues and low voltage problems wiping them but they are also a very popular computer for LS engines.

Love MoTec, just not the right application for this.
