i have decided to upgrade my boost control on my 89 2wd saff cossie to an universal electronic apexi version, looking at the fitting instructions it doesnt look too bad, i have one problem, it splices into ecu wires and i dont kno which wires do wat on a l6 ecu.

rather than me testing the wires for a few hours, it would be appreciated if anyone could supply me with a detailed ecu pin diagram.

the specific wires i need are:

ign power
rpm signal
injector signal
earth
throttle signal
speed signal

as there are no instructions for a cosworth and only jap cars, any additional problems/ information would be greatly appreciated

thanks

ign power 20 i think , check with multi-meter
rpm signal Splice in wire from Tacho - think this green? (may cause signal to be wrong on tacho, don't know as i use the AVC-R as my tacho)
injector signal Don't need if using RPM (best way IMO)
earth 1 or 19 - again check with multimeter (if you also wire in the scramble switch - much recommended use the same earth for this)
throttle signal 17
speed signal N/A on L6 as standard


Not 100% sure as its from a scribbled diagram i have here, but all points are easily checked as yu do it if you use a mulimeter and the AVC-R also has a diagnosise menu to see if you have the sensors set correctly.

thanks for the info m8, did you have any problems with the avcr on your car?

i gather i dont require the existing amal valve too

nthorpey

No problems at all.

You will only need to use the solenoid included. this pipes between actuator and compressor housing

the throttle reading is permanently showing 100%, weird stuff, i have double checked the wiring and i have connected the correct wire to 17.

any ideas?

plus how the hell do i adjust the boost with it? i've tried adjusting the a and b settings but it makes no difference, it wont run anymore than 1.5 kg/cm of boost (according to conversion charts about 22psi)
and it doesnt always go this high

i am running a t35 hybrid with an almost fully wound in actuator rod on a -34, before the avcr i could run at least 28 psi if i wanted to through 2 stage amal valve

cossiedaz

all sorted!!!!!, i had the pipes on the solenoid the wrong way!!! bloody japanese instructions, the throttle sensor just had the wrong setting!!

nthorpey

When i set mine up ai had A as high boost setting (dry conditions) and B as lower boost (wet setting) or if someone else was driving

Also scramble switch was set with a rising rate of boost for a couple of seconds to act as a type of launch control so that it didn't rip tyres and gearboxes apart.
