Most people can tune a stock computer with more than adequate results. For 250 you can buy a qh and tune it yourself. Unless you need specific features the Holley offers, i don't see the point.
Sounds like bad caps in the ECU.I received my Terminator X max a couple weeks ago.
I was using 1994 ECM and SCT chip, car would either start and run perfect, or overfuel and stall. I was chasing my tail trying to diagnose the problem, when all i wanted to do is drive the car.
The moates/tweecer stuff is cheaper, but the learning curve is steep and not many tuners around here that i would trust to tune the old stuff.
The term x max solves a few problems for me, new ECM and wiring, can control the trans, has a display, and can tune the car. Also can handle future upgrades as well which I have planned.
I'm taking my time installing it, i had to replace a bunch of sensors as i was still using 1994 sensors and the Holley harness connectors would not fit. MAP and coolant temp are all that need connected for the engine, then can start working on the trans wiring.
I'm glad i ordered when i did, writing seems to be on the wall for this type of equipment. I'm excited to get the car up and running again so i can drive it!
What do you mean??? the holley tunes itself LOL.... Go over to the holley forums or to any of the FB pages who specialize in Holley and see how untrue that really is.Start up tune is simply done by the wizard via hand held if you want to. Some folks like to go a bit deeper to get started off. I wish ya'll would realize nothing is automatic and all knowing. At this point it's comical ignorance.
Thats my point. It seems to really depend on the combination. I dont personally have a Holley but I have a few friends with it. One of my friends has issues with what sounds like transient fueling and tip in (based on his description of the problems) while another swears it just tunes itself and works great which is pretty much par for the course for any tuning application. I think it really depends on how mild or wild the application is. I am helping my friend build a fox with a twin turbo 'yote and its using a termi X to control it and shooting for 7s. Im looking forward to getting my hands on it so I can get first hand experience with tuning a Holley.Seems like some people have problems and some people don't.
My best friend swears by them and says the same thing. He owns a shop here in town and has installed a couple of them on stock LS swap cars with good results apparently. At this point, im basing my opinion on what I have seen on the forums but I will be getting first hand experience with them so my opinion might change. With all tuning, it comes down to setting up the initial parameters correctly and I wonder if people who have issues arent getting them setup correctly to begin with which is where the problems come from. That is of course speculation.Fwiw we did a terminator x max on a 78 corvette with a 6.0 ls and 4l80e. Once we set the throttle blade it did tune itself. Just used the handheld and drive the car around.
