Could be damaged during transport as well... I asked CMS to flash the other ECU to see if the ECU is the case. Should know what's up then...
Supercharged from Holland...

Finally some (good) news: I got the car MOT'd today and got Courtenay Sport to do the final map. Map sensor was broken and some wrong bolts were used on the inlet manifold so that wasn't sealed properly. Runs really smooth now... Really glad it's finally running like it should now after a lot of hassle... Results are 248.87ps and 221.87 lb/ft.

Blowing a lot of dust from this old topic... Over a year has past since the last post! @evocarlos excellent threads inspired me to update it.
Anyway, here are some updates of my S/C project.
I've put on a much bigger Intercooler to get intake temps down:
That needed a new bumper which was big enough to fit it in. I chose the Prodrive one from the Astra Sri-t. I mounted a cold air in take where the fog light was and put some new mesh on it.
The guy I got it from assured me it was colour code Z157. sadly it isn't... However I must say in real life it is less noticable than on this picture.
Then I decided it was time to get the software sorted. Cold starts weren't good and the idle was lumpy. Then during a MOT the O2-machine showed it was running lean. OBDTuner (www.obdtuner.com) is available for VX220 / speedster with the z22se engines. This software turns the z22se ecu in a fully self programmable device. With no local tuner nearby that could handle the z22se ECU the self map option of OBD tuner was very appealing to me. It also has lots of logging parameters:
Because it's based on the Original software for the vx220, cruise control isn't supported. Other than that, I'm well pleased with it. Engine runs significantly better with it, no more odd cold start and it idles really smooth. Because of the logging from OBDTuner I saw the z20let injectors were almost at 100% duty cycle above 5300 rpm. This made me fit the bigger VXR injectors:
I also installed the Original LSJ TMAP sensor which has a built-in temperature sensor. Because this is placed after the supercharger instead of in the air filter a much more relevant intake air temperature is measured. Which gives the ECU a better image of what's going on so it can act accordingly.
And this is how the engine bay looks now:
Here are some other screenshots from OBD Tuner. Adjustments of throttle response:
Lots of parameters to self-adjust. No need to go to a tuner to do this for you:
Fueling tables:
Well, that's it for now. If I can be of help to anyone, please let me know. I'll try an do better at updating more frequently

Yes it's really tight. Had to trim the inside of the bumper to make it fit.
