hey all was wondering if anybody has wired an ems stinger into there vl and could help me with some wiring probs
i.e what factory color wires for
Crank angle sensor
what is trig
what is sync
and what is 12v
and Throttle Position Sensor
what is +5v
what is Signal
and what is ground/earth
and what happened to the fuel pump as i beleive it was controlled by the stock computer
any help would be greatly appreciated Cheers
The factory TPS is not a variable resistor type sensor. It has 2 contacts - 1 for idle & 1 for full throttle. I'm guessing the EMS requires a variable type sensor?
Fuel pump is controlled via the fuel pump relay. The relay is fed constant 12v and the ecu switches it to ground via the dark green wire.
u need to set the base timing to 60degress btdc as ems reads differnet factory computer. which is 10degrees btdc aswell. stingers a gay also only have two boost tuning boints, should of got a microtech for cheap computer
His running a STINGER,not the older type EMS, they have unlimited boost points,eg if you want 12.8 psi,15.2 psi,20.9 psi etc etc You control boost points and etc.
As for you TDC did you modified your dissy???
Ring EMS, they have diragrams to do what your doing,
when i did mine they sent me a diragram showing me which colours to connect!
Eg. ems pink to std vl blue etc etc
EASY!!!!!!!!!!!!!!
how to i set the the timeing . do i set engine to 10 deg btdc and them take dizzy out and set to fire at piston 1 and thanks heaps jetfj ill ring them tomorrow but one more question did you have to replace your tps with a variable type.. or is tps Just for idle control
and what is meant by modify the dizzy... how do i do it?
thanks all for tha help
dont worry 2 much about variable tps just use factory one
about the timing the stinger needs to be set at 60degrees base timing, hooked one up on rb25 and had to modify crank sensor but should be easyier with vl dizzy, ask the ems dude if u have trouble
just outta curiosity, whats this ecu worth these days - either brand new or 2nd hand. my bought my car with the 4424 fitted and tuned just curious what the ecu and loom is worth.

You cannot use the factory TPS. Like i said before, the factory tps is basically a 2 position digital switch.
The stinger uses an analog 0-5v signal.
Um worth about $1200 new i beleive, picked up mine for $800 with loom and comp cable had been on car started then removed never actually used or programed to drive. have come to the understanding the ems doesnt even need a tps and am definate it doesnt need an o2 sensor so im guessing it just runs of map sensor to adjust ignition and fuel is that correct..
