FiTech EFI system
Im debating about picking one of these units up. After reading thru this entire thread, I have to say Im very leery. It seems like a lot of messing around just to get it to run correctly. The reason I was thinking of going with this unit is because Im tired of messing around with carbs. Well it seems like there is a bigger risk of getting stranded or not running correctly with this. Like Johnny mentioned you dont hear about the people that are happy with it, just the ones that are having problems. I was also under the impression using the FCC you didnt need to run a return/vent line and now I see you do. My tank is not set up for it and if this is something that must be done then that is even more cost to the system. I guess Im looking for someone to convince me to go with this unit now. Im also curious if anyone has seen an increase in MPG's out of this.
I think I was one of the first , at least on this website, that bought, in August of 2015. I had some issues with mine, and eventually had to send the throttle body back for an ecu upgrade. Mine just kept kicking O2 sensor faults.
I would not be going back to a carb.. Too much tinkering if you want everything to run just right. Tinkering on the handheld controller you will do, but way cleaner. Does it work perfectly.. not yet, but sooo close. think it's a little rich? change the AFR at the side of the road. Need a bit more fuel on acceleration? Change the accel pump settings till it's better.
For me , winter and colder starts were always a problem.. not any more.. starts at -25 celcius, with the block heater plugged in and runs with no stalling without touching the gas pedal. Car has never run smoother..
The "dreaded FCC". Sure you need a vent line.. But i have never had a problem with it. Is there gas going back to the tank ? Don't know..Probably, but that's what the line takes care off. Reducing the Fuel pump numbers as Fitech now recommends I think keeps it all cooler.
I have never been stranded. I believe there is even a limp mode, just like newer cars built into the ECU. Good luck with whatever you decide. !!
Now can someone move us into spring to I can get back out there !
Straightline!! pop up to Winnipeg and I will take you for a spin!!
