Does anyone have any experience with both, either, or? The mechanics of swapping a 5.3 4L60 combo into an older truck, i am good with. The turning off the VATS and unnecessary extras i am not to comfortable with. Engine swaps to me usually involved smallblocks (ford or chev), this is newer territory. Thanks for any input
I use HP Tuners. Never done the VATS thing, but I just tuned the new cam/heads/header combo in my 6.0.
I think they're pretty similar. Both are well supported and have strong support online.
Either way the learning curve is pretty steep, but the amount of stuff you can do with them is almost overwhelming. Awesome stuff.
In the long run Holley HPEfi may be cheaper. It's definitely easier. If you're only trying to turn off the VATS then no, but if you need to tune then once you account for dyno time etc Holley is hard to beat.
Well? There are no local tuners, and I know if i can figure it out it may lead to more side work and ultimately more money for myself and Mrs Warpedredneck! LoL,
I have HP Tuners experience.
Plus: Seems to be the industry standard. Disabling VATS takes literally one click (change VATS from "CAN" or whatever to "None") and everything else is similarly simple. Am seriously contemplating using a GM PCM on at least one of my Volkswagens because the sky is the limit with what you can do with some of the computers when you really get into it.
Downside: Cannot write just any VIN to the computer, it has to match the vehicle type that the operating system is for. With EFILive you can write a Firebird VIN to a Silverado computer, or even write a BMW VIN for that matter. This is important if you have emissions testing and they VIN-check the computer.
I don't know how EFILive does things, but HP Tuners basically is two credits ($100) for every PCM you register. PCM's serial number is registered, and tunes must be from a registered PCM, and if not then you have to register that tune's PCM serial number as well. In other words, if you download someone else's tune from their Registry (or anywhere else) and want to use it then you are out 4 credits, two for your computer and two for the serial number attached to the tune you are trying to write. The Pro package comes with eight credits.
The Registry is nice. Lots of bone stock tunes there. Let's say for instance I convert a truck engine to LS1 intake and returnless fuel injectors/rail. I download a stock tune from an LS1 engined Corvette, and just copy all of the various injector related tables. You can read and copy for free. Click click, copy and paste, more click/copy/paste and then burn the new tune to the PCM, and we're done.
Simple things like disabling VATS or changing the gear ratio/tire diameter is really simple.
i really like HPtuners. the click/copy/paste is awesome. i was working with an ecm that some unknown jag tuned, and everything was way off. i found a stock camaro ls1 program for the year of my engine, copied and pasted all the fuel and spark tables, and immediately got the car running a million times better. plus i could turn off the rear o2 sensors and sell my simulators that i bought, and a bunch of other stuff. i've corrected my speedo too.
thank you folks! this is all helping!
