Look under the dash, there should be 2 sets of connectors.
A green pair (2 pin T shape plugs) and a black pair (just single pin)

Connect the green pair together to check timing.

the turbo is 20 but not n/a

test mode connector to check timing? I did not know that ! I have not done that either ?! I did however find the green bridge test coonectors for ecu 3 plug ecu diagnostic mode only when i dropped the fuse box - it was tucked up behind and maybe never used before !!

WHO HAS USED TEST CONN FOR TIMING EA82T's ?

If your car is an 88 or newer, also known as hotwire or 4 plug, you should connect the green connectors and your timing will be 20deg, turbo or na.

If it is a 85-87, it will probably be 8deg na, 20deg on turbo. But seeing as these models dont have a timing map, you should disconnect the vac line to the dizzy

Mine is an 89 model, on the underside of my bonnet, it tells my to connect the test mode connectors. (ie. to lock the timing static and ignore the timing maps)

i found the green connector but mine has double brown instead of green

seems to be running good now though i just adjusted it by ear and it has all its giddy up back which is good because it was drinking lots of fuel

don't really know because when i connected the green plugs it made no diffrence to where it showed up with gun

as far as where it is positoned it is off the scale but it running really well with heaps of power if i manage to find which plugs to join i will post where it is sitting

4 plug mpfi

Advance is an ecu map, controlled by factors of load, tps, temp and rpm
