[94 rs tt to st 1s conversion problems]

Earthing changes done...I happened to use a cam angle sensor from a v8 wrx....are they the same? Mayb y we have no spark? I know the cam gears are different. ..

As for 3 plug coil....I can bypass the ignitor all together?

Fuel pump is priming n we hav injector pulse..

cam sensor did come up when we were doing the earthing wires. stayed on until we changed to another cam sensor...but now no spark pulse...so mayb hav to change back to old one and try again

[94 rs tt to st 1s conversion problems]

hi all need some help on this

car is 94 rs tt manual and i hav done the usual mechanical side for single turbo conversion using same motor to run 1s yellows and orange afm.

for wiring side we have done the 4 plug to 3 plug following gazzy's thread. we have also done all the earthing mods to it and the 1s ecu is not giving codes when on. however when we go to start it,only only number 3 cyclinder is firing.strange as 1s runs wasted spark so ideally should run cyclinder number 4 on other side? at first we were using tt ignitor and coil on plug setup.then we tried to bypass ignitor and run the newer 3 pin coil on plug with individual ignitors.

on gazzys thread there wasnt much mentioned about using stock ignition?do i hav to run wrx/sti ignitor and coilpack with leads for it to run?

we traced the two ignition pins from the ecu through to the plugs and doesnt seem to be pulsing?problem with ecu?

another wire we were thinking to check was the ignition power for the ecu?mentioned on the thread about it going to drivers floor by the fuse box? DOES THIS WIRE MEANT TO BE HOOKED UP?

any help please?
