Apexi to Haltech

Just wondering how simple or not simple it would be to covert from my current Power FC to something like the Haltech Elite 1500 and what that process might look like.
Thank you

Relatively simple depending on what you had to hack together to make your PFC work. There are patch harnesses to run to a haltech and the base maps are relatively good.

hack together? pfc is plug and play.... even in the fc. why would you say hack together?

switching to a different ecu is as simple as unplugging the old one and plugging in the new one. you dont have to do anything extra. of course this only applies to plug and play ecus. if you buy a wire in one then you will want to look into a patch harness to save from buying a new harness

Should be easy to do. Buy the Haltech Elite 1500 + the plug and play adapter kit. Talk to your tuner first.

Because its not completely plug and play, certainly not on an FC with a single igniter on the trailing coil pack and the requisit flip/flop switching the stock ECU does. The few wires that do need to be pulled or swapped on an FD are completely minor but I've seen countless 'installs' that involved cutting and electrical tape. Thats what I mean by 'hacked together'. Not to mention the hacks people implemented for boost/twin control when people didn't understand the PFCs control strategies.

i think you're being dramatic.... its 2 or 3 wires that you have to cut to use it in a usdm and then you plug it in to the stock plugs are done with it. going so far as to say hacked together is like saying going single is rigging a turbo to the motor.

You may think whatever you'd like, I've seen more than a handful of these things beaten up because bubba and his friends cut said wires with a chainsaw rather than de-pinning, then couldn't get boost and turbo control to work so Profecs were used and again installed with duct tape and chewing gum, then 'Oops, AC and the blower fans are ***** and don't work with the plug and play action' so out comes the chainsaw again to potentially add the requisite diodes etc. It adds up, and a lot of the time it's a complete **** show.

Don't get me wrong, I'm not saying there's no place for a PFC, or that they HAVE to be hacked together. It's quite easy to install them well, but people are ******* morons.

There fixed your answer for you....

BTW what you got against chainsaws? Even my friggin chainsaws are cool. One of my 372xp's has a custom popup piston, with squish clearance machined along with a full port job on the intake and exhaust. only thing I have not done to it is put a tuned pipe on it.
