Reset ECU. What driving pattern to get most power?

Hey Peoples,

Was wrapped in the performance of my EA until I recently reset the ECU and noticed that i had less power.

Even after lotsa driving it doesn't seem to have any torque down low, nor does it rev as hard as it did before the last reset. At least the idle is stable now which it wasn't before.

Whats the best pattern to stick to while in learning mode to get max out of it?

Btw.. EA S with 5 speed manual and CFI

Jamie

Re: Reset ECU. What driving pattern to get most power?

Hi Eskyboi,

It's obviously odd that the power has dropped since running a reset, but have you troubleshooted this problem from any other angle: ie checked ignition timing, fuel mixtures etc? I once had a similar problem in my previous car (a Nissan Pintara). I was convinced that the problem was to do the with throttle position sensor (registers a 0 - 5v signal to the ecu - just a potentiometer). I replaced it, changed the plugs etc, but to no avail. After reading through the factory Nissan service manual, it turned out the ignition timing was out by about 7 deg. Advanced the timing, and the problem was fixed.

Possibly try a higher octane brew in the tank and reset again? Do these engines run knock sensors?

You have an EA S with CFI? How did this come about?

No EA's dont have knock sensors.

EA's did come with CFI, but it wasnt taken up that often.
Was only on the EA 1's.

CFI was standard (MPFI optional) on GL/S/Fairmont through to EB series 1.

Are you sure? I'm pretty sure all S Packs came standard with MPFI.

I know the S Pack did not come standard with the MPFI, but i didnt think the CFI lasted right up until EB1.

dont reset your ECU.. what you need to do is.. reset it and start from scratch now that u've done that.. but after its reset u gota drive it as hard as possible so that it learns that thats the way it should drive.. in bout couple days/weeks it will be going hard as possible. then renember not to reset it.. because its constantly learning. when you reset it you make it a fukn peice of shit til you retrain it.

Yes it certainly did, the phrase "what were Ford thinking?" comes to mind

I previously advanced the ignition timing to get the last lot of power.. wondering if you could advance too far? Its not pinging at all.

Now the idle is hunting again. I'm hoping it will sort itself out over time.
