vs manual ecu

[djbrooksy]

what type of output do you get from a MAF sensor ??

cause if you track D1 it ends up at pin 2 of U5 in much the same way as D2
it uses the cap and diode that are on the auto board in that corner to start with

[VL400]

Its a square wave much like the manual VSS. U5 might be something like a 74HC04, but a custom pin out. Am not certain but it does look like a buffering chip.

[djbrooksy]

well what ever U5 is thats where my skills and tools let me down
they get me into these types of mess but fall short of getting me out

i might go see what the wreckers want for a vt pcm to study

[djbrooksy]

well the wreckers want $150 for a pcm so it stayed there at this point

vl400 have you had any luck and or time to do any more testing ??

[delcowizzid]

last time i traced an auto pcm manual vss input pin it went straight to earth if i remember right

[djbrooksy]

both vl400 and i have tracked it to pin 6 of U5 but where to from there i have no idea

holden202 OSE bin/cal for the ecotec is starting to look good
cause the more i think about it all my findings are from looking at a vt pcm.
and there is a fair chance thats all wrong cause as i understand the
vt pcm cant handle the t5 VSS as the where only fitted with the getrag and they run the same type
sensor as the auto

[VL400]

Not tried it yet but will during the week.

This is interesting the fact you have the same error my mate is getting (94) with a Manual ecu and a manual Memcal. Keep in mind yet to check over the wiring completely but the ecu he has is a 16250728 with a BZPT memcal which is listed as a Getrag box and not a T5 like he has installed. And from what your saying about the vss it won't work with the T5 unless some mods are made.

Edit
Should note ECU Service number is a 16199728 which is a VS Manual.

[VL400]

Getrag and T5 use different sensors, the getrags are magnetic so they use a specific manual memcal to suit - it tells the ECU its manual but to use the magnetic (same as auto) input.

oh should have added that the memcal has been replace with BWLS1281 program on a Mod memcal after finding out it was for a Getrag. Thinking it was still the same ECU as a T5 and all it was just be a matter of using the correct memcal program for a T5 but after reading http://www.kalmaker.com.au/phpbb3/viewt ... ?f=2&t=834 i think I'm in the same boat as djbrooksy
