Never had a single problem.īut, if you are set on using an aftermarket system, then definitely use Holley. We’ve been developing and refining ECM tuning and diagnostic support for General Motors for. Avoid having to buy additional software programs, learning how to think in computer code, or relying on a questionable 3rd party tuner. HP Tuners offers the most comprehensive diagnostic and tuning software for GM vehicles in the industry, from the 1997 Corvette LS1 to the 2021 Camaro, 2020 Colorado, and the 2017+ GMC Sierra/Chevy Silverado 2500/3500/4500/5500 6.6L Duramax (diesel). No thanks.Īs far as DE and racing goes, I've built several cars for that using the GM ecu. No dyno, no tuner, no factory re-flashed ECU The FiTech 70051 Ultimate LS Standalone EFI ECU kit is the ultimate LS swap computer for DIY enthusiasts who want full control over their engine and transmission. Plus the fact that you have to build the wire harness from their kit, and it appears to require external components to run the coil packs.
I've never heard of Performance Electronics, but after looking at their website, you would pay a lot more money for the same thing you get with GM stuff. For a few hundred dollars, you get a system that is virtually bulletproof. They are very good, with lots of tune ability. In all honesty, I would stick with the GM ecu and a good standalone harness. Would love some thoughts from some of the more experienced DE guys! However, it's about double the Holley system in price. It includes everything you need to make an LS run, including a single, state-of-the-art ECU that manages spark and fuel delivery with an optional transmission control feature for 4L60, 4L65, 4L80. Everything is custom, big race team type stuff. It's probably a little over the top but they are SUPER helpful and would handle the install and tune in their facility. Soo.for primarily track time, do you think I should pivot once again to Holley or FAST? I also had considered this company here in Cincinnati called Performance Electronics. I have a re-worked L92 that I'm purchasing from a guy a met at the PRI show, who is going to run it on their engine dyno at their facility in MI. I was back and forth between Holley and FAST and recently canceled orders for injectors and an LS3 intake to go with the FiTech kit.
