EFI connection and FAST Seriously considering the new EFI connection 24x conversion for my 355 build. Does anyone know if this system will jive with a FAST or accel standalone? Really dont think an LS-1 ECM is capable of the hp i am looking for here. Thanks
Just make sure you wire the harness carefully and have the proper bank assignments.

Looking to make around 1000rwhp with a PT-88 and my built 355. This Ls-1 ecu thing is news to me. Im very interested in a EFI connection system. IF this is more than doable what program do you recommend for tuning. I live in phoenix and it seems people only deal with FAST and Accel. I have both systems but hate the fact I have to have a expensive custom harness built to retain my gauges and A/C. Any insight on this would be greatly appreciated. Thanks!
Well I just brought the complete EFI Connection 24x kit with all the bells and whistles, the custom engine harness, 01 LSx pcm, billet timing cover and modded cam sensor housing and the 24x reluctor for the dr timing set I'm running on my 383 LT1. I'm waiting for all of it to arrive, they recommend EFI Live for tuning software and I sent my PCM to (doc@efialchemy.com) for a base tune customized to my setup.

I hope this helps.
If you require higher resolution, you could run with 58x equipment. Personally, I don't think I would...but it's now an option. Bigger (58x) is not always better (than 24x). The Gen IV GM ECMs can be more challenging than the Gen III GM PCMs.
So in this case, if the FAST ECU can operate a Gen IV LS engine (LS3/LS7), then you can run the same FAST ECU on a 58x LT1.

When the LT1 is equipped with the 24x components (24x crank sensor/reluctor and 1x cam sensor/reluctor), electronically you can consider the engine an LS1. And if the FAST ECU can control an LS1 engine (and it can), then it can control a 24x equipped LT1 engine. And this is a bolt-on crank/cam signal solution. No messing around with signal adjustments. Bolt it on and you're ready for the harness and ECU.
