Standard ecu for engine dyno

[The Beardo]

mste and I were chatting earlier about his 172 engine his building and wondered if he could get it running outside of the car? I know the engine would need the ecu but would it need the UCH box or is there aw way of just wiring up the ecu to get the engine running?

It's a big and expensive job to get an engine, especially a larger car engine, set up on an engine dyno for short-time use, plus, unless you have your own dyno, finding a company who are going to let you do a few runs won't be easy. Just a heads up it's most likely more hassle than it's worth to run the engine outside the car and probably far more economical to build it outside the car, do what you have to do and plonk it back in and take it to a rolling road, then go from there.

Things that could possibly give performance increases seem fairly well documented and trusted anyway, so if done right you *should* see the same results. My 2cents

I fully understand your point and agree but just wondered if you'd need the UCH as well as the ecu to run the engine or if you can just power up the ecu

phase 1 or 2?

Early Ph2 172 (02 I believe)

logic dictates you could run it with engine loom and ecu etc but you'd need throttle pedal or at least a signal for the throttle body. afaik despite canbus not finding the bits missing it should run but i could be completely wrong though.

just stick it in the car inless you want to pointlessly part with a large sum of cash.

ok so how do you get the Ecu to power up and how do you bypass the immobiliser!, is it just a case of giving the Ecu a 12v feed and the tdc sensor a feed aswell?

 

[bloke]

got to say pass on that one, not sure what the ecu needs to see from the uch etc...

It would need a key and uch wired up to allow it to run
