Stuff i need (just to make sure)

[CASPERAMC]

ok im ready to buy my megasquirt and i will probably be installing it in 3 weeks but i just want to make sure i am getting the right stuff.
right now it will be going on a fairly stock 2004 2.0 NA. i want to have it tuned to the motor with the walbro pump and stage 1 injectors that i will be using when i swap in my newly built motor, so that when i swap, it should start up with the megasquirt and i will only have to worry about fine tuning it. so just to make sure i think i need:

ECU with 4.0 bar map sensor:370
http://www.rs-autosport.net/catalog/...roducts_id=210

Universal Wiring harness:53
http://www.rs-autosport.net/catalog/...roducts_id=229

GM Coolant Temp Sensor, w/ Connector :16
http://www.rs-autosport.net/catalog/...roducts_id=215

GM Intake Air Temp Sensor, w/ Connector :21
http://www.rs-autosport.net/catalog/...roducts_id=216

Total:460

i read that someone had a way to use the stock sensors. any progress on that? id rather use the stock ones than spend more money on unneccesary things

thanks

http://www.megamanual.com has instruction on how to use the megasquirt with stock sensors. You just need to take measurements from your sensors to get the resistance curves.

ok then i can probably do that for the iat sensor but if i use the coolant sensor, i heard that my gauge wont work anymore because there will be nosignal going to it. is there a way to share the signal?

"Sharing" or simply tapping into the stock signal wire will result in a non-functional guage in your instrument cluster. I was going to try just tapping the lower coolant housing and having both the stock and GM coolant sensors plugged in. I may do the same for the IAT and make it even easier for me to switch between the two in case of any problems.

K i am about to order my stuff as well...what about the tps sensor...do we need to buy the GM tps as well? I spoke with a friend who has wired many many megasquirts on 1st gens and he said to definitly get the gm air and map sensors...I was wondering about the tps or does that matter?

Stock tps will be OK

Peter, Yeahhhhhh, I'm gunna need you to go ahead and fill out a TPS report after you fix that problem. That'd be grrrreeaat. Don't forget the cover sheet.


Sorry, couldn't help myself.
