Swift mini problems

choochoo · 12-07-2017, 08:29 PM

Is there anyone good with ecu for the swift gti.
I having ecu problems where my limiter cutting in at 4,900 rpm.
I have two ecu one works one doesn't. One I found has a link wire across circuit board that don't look right. I removed it and the car starts and cuts out. The other ecu that didn't work I soldered the wire in and it now starts the car and drives but againhitting limiter at 4,900 rpm

Looks like it's connecting to B1 which is cam sensor in the distributer.

Yer that's where we traced it to. I removed that wire from ecu and car starts then cuts out. So i fitted it to the ecu with out the wire the. That ecu started working. For some reason that wires there and not sure why

Looks like there is a component on the other side of the board that goes from the end of resister R13 and finishes next to the pin B1, I think this might be a damaged (maybe a diode?) might be worth opening it up to see if there is obvious signs of damage.

I have to put that wire on both ecu I have to make the car run . Makes me wonder if there's a wiring fault

I think I once blew a diode in that area when messing about with a harness just stripped from a car(trying to power it up on the floor)
It may well be the case the harness has a fault. Need to go through and check the harness based on the above pinout.
