This is not to anybody in particular... but I think some of you guys don't understand how a car ECU works.
First of all it is designed so that the same engine can operate in different parts of the world, different climates/elevations ON THE SAME ECU.
Just think about it, you can drive an Accord...
Yes it is easy to do with OBD1... but with OBD2 I don't know any mechanic who would risk it.
Or are you talking about the visual part of the inspection? Then yes, the visual part will not be a problem.
IC,
It would be pretty cool if I could build an F22A and be able to pass the OBD2 inspection with it.
Theoretically it should work with the F23A5 ECU... and an F23 or F22B OBD2 distributor...
That would be risky though, I wouldn't want to build an F22, put it in the car, and realize...
1. I've personally ran a stock F22 ECU on a built ~11.0:1 compression motor, it ran fine. I just needed to get the car from one point to another and kept it under 3000rpm, it drove fine... I've never done it with OBD2 but I seriously doubt a very small change in compression is going to cause a...
Well I don't think it takes hours to convert to OBD2 and back. 15min to change injectors, 5min to change the ecu, 10min to disconnect charge pipe, another 10-15min to change a couple more plugs like the IACV etc.
From my experience you don't need to drive that many miles in order for the ECU...
It may not be as easy as I think...
BUT this is what I am thinking... changing the engine compression from 8.8:1 to say 8.5:1 shouldn't make much of a difference, the ECU will not be able to tell the difference.
Say you did absolutely nothing to the engine besides lower the compression by that...
I appreciate all the responses, seriously.
Just can't understand why somebody would tell me that I can't run a built turbo motor on the stock ECU when I already made it clear that I will be running OBD1 and have extensive experience tuning boosted engines. Sorry If i was being rude though.
The F23 already has low compression, there is absolutely no reason to lower it even more. I'm pretty sure even off-the-shelf pistons don't lower it a significant amount.
:bash: You have to be kidding me! Please show me where I said that I will be running the stock ECU.
They don't have...
Yes, thanks, now looks like this should be a pretty straight forward build.
So from what I understand you are running the stock F23 cam?
You have to:
1. Put the stock ECU back in
2. Convert everything back to OBD2
3. Put the stock injectors back in
4. Remove the spring from the wastegate so...
not making a thread but if you seriously think I am making stuff up, here is a pic of it
I LOLd !
This isn't rocket science though...
I can write out the whole process right now in 5min....
- get pistons+rods
- send block to machine shop
- send head to machine shop
- put head on...
