Engine light andStalling issues after manual conversion

[johnsy_vs]

Hi i have just converted my vs series 2 commodore to a t5 manual. i have plugged the manual ecu strait into the auto harness.... do i have to do anything to the wiring to prevent it from stalling? all help apreciated Thanks.

[johnsy_vs]

getting a manual wiring harness for $30 im happy its just gonna be a bi#%h installing it lol

Cant you just use the wiring guide that in the conversion bible ?

Is there something more that the wiring harness does ?

you didnt just get a getrag manual ecu not a T5 one

[johnsy_vs]

its a t5 ecu all came out of the same running car... and nick it was just easiest for me to buy the harness concidering it was only $30, i heard they can get up to like $150... and never heard of the conversion bible lol... sorry if i sound like a retard...

Not a retard at all Johnsy, I have a car that had a conversion done before I got it and wanted to know if there was other things that still needed to be done.

Cheers

Friend did the same conversion few weeks back same problem as yours turned out to be IAC.

You'll have to wire up the vehicle speed sensor to the ecu properly. The engine light comes on when you're slowing down and it stalls when coming to a stop, correct?

[johnsy_vs]

correct maldotcom2 and whats an IAC? lol Cheers!

Idle air control. It's a sensor that bolts to the throttle body.

i had the same problem been stumped for months, car drove fine idled fine but stalled when coming to a stop and light came on looked at the ecu loom and a wire was out turns out the purple white wire for speed sensor put it pin d2 thought bingo, still no go the wire was broken 6 inches up the loom and joined bodgey soldered it and works fine. without speed sensor the injectors dont cut out on deceleration and when u come to a stop the IAC opens up for a little more air, but without it it just floods it asnd conks out good luck mate

does this apply for autos too? mine trys too stall when coming to a stop and when you say injectors dont cut out when decelerating might explain why the revs go up and down from 1500 to idle constantly when backing off.

I got that problem to where the idle moves up and down as I slow down but idles fine when stoped in or out of gear, Auto. Would this be the same problem?
