How to convert a 202 to Delco

Thanks Vlad, are the VT ones the same. I can get these easily. I will check this one out.

From memory the ecotec works in your favour on the VK set up duebti the opposite opening direction of the butterfly?

yep ecotec throttle body is a good option!

Thanks for you help guys.

Just a quick question. Are the grounds within the ECU all common , ie is the ground at A11 (MAP/MAT sensor gnd) physically the same ground at D2 (TPS/CTS sensor gnd). The reason for the question, for physical convienience, I would like to use the TPS/CTS gnd for the MAT sensor gnd. I assume this should be OK.
Cheers

i remember looking at the PCB of the 808 and noticing all the grounds together grounded to the same points on the PCB ... but i cant tell you if that goes for those ones ... but more than likely.

Is there a reason you don't want to use the map sensor ground like stock to share the return voltage over more wire to stop voltage offsets

Thanks, I will check it out when I am putting the NVram etc in.

Only because I forgot about the MAT sensor when I made up the loom and I only have one free space in the connector which I can use for the MAT sense but no space for it's related gnd. If I can piggyback the MAT gnd off the TPS gnd my problem is solved without having to have one divorced wire on a single connector. Just tidyness.

It can go all bad if you share grounds with a different POWERED circuit like MAP or TPS etc since the IAT and CTS is a thermistor circuit. You can check at the ecu/pcm if it cares by using your ohm meter to see if those grounds are all tied to earth together. Some care, some don't.
