got the car running again now but it seams to be running rich , from wat i understand for the l6 ecu their is a white screw on the ecu i turn it a couple times clock wise no change , another thing its idleing slow not sure how to raise the idle.

 

Clockwise will make it richer IIRC What chip do you have in the ECU mate?

The idle screw is under the throttlebody, but you idle can also beaffected by an out of calibration TPS.

 

Not sure wat chip but I wud think standard and how wud I recalibrate the tps

 

There is a base idle screw on the T/B as said, if 2WD you will have to loosen the locknut first, be SURE to retighten it properly though otherwise it can fall out and they are hard to replace!

Be careful also with the CO screw, this gets it's name the global mod for good reason, as it subtracts a percentage from the fuel table, so you could end up running lean up the top!

I would also like to know how to calibrate the TPS, I know you have to remove the T/B to do so though! I think there may be an allen screw.

Basically the output should be .5V at wot and around 5V when the throttle begins to open (2WD) 4x4 is the reverse of these figures.

i found that my c/o screw just keeps going no matter the direction and since the ecu does not use a lamba configuration i fitted a o2 sensor to the car but i can seem to get it to work its a autometer kit when i connect the powers the gauges lights up and reads rich but when i connect the signal wire the gauges blanks out cant figure out. and to paul if it s has a standard chip what should be marked on it.

 

Please tell us your spec.

 

um not sure of the engine spec , but from wat im told its standard but pull down for an over haul probly early next year, right now im trying to take off the ecu cover to check the chip but the dam screws come come out

 

got the cover undone i guess this should make sense to you guys the chip has on 3 Bar 803 level 6, i also have to other ships here with: No . 8 403 w/s 0626 3 bar and SAPL2v4 from grahme goode racing

 

are the 403 injectors the dark greys every one wants??
