Hey everyone,

I have an M48 and am at the point where I want to start my car. I am going to be finished my wiring and installing all of my gear soon, in the car I have

* Garrett GT47
* 272 Jun Cams
* 1600CC Injectors
* 2JZ GTE Engine
* m48 (obviously)
* CP pistons
* Denso coils
* Weldon fuel pump
* Wideband lambda
... in a Toyota Supra.

I've already got a starting file but I get the problem with switching the car on. I took the Motec course in Melbourne but still am a bit worried to get the car started as it's my first start up using the Motec ECU, I don't want to blow my engine or anything but would like to do it myself.

Does anyone have any info on things I should do for start up? I'd be happy to stay on the safe side, I don't need it to fang off down the street after the initial calibration, I just want to start it up moderately so it will run and then tune later.

Thanks for any help, I really appreciate it.

Make sure that you have done an output test so that you know that all of the output functions are working and that the ignition and injectors are wired in the correct firing order. Test the fuel pressure and measure the fuel delivery rate (from the return) to make sure that the installed fuel flow is sufficient for your engine. Remove the spark plugs and crank the engine until you have oil pressure. With the plugs removed check the CRIP with a timing light.

If this is a fresh engine do not let it idle for too long, check for leaks and allow the cooling system to bleed and reach opperating temeprature. I would always prefer to get an engine on to the dyno to run it in. You are unlikely to do damage starting the engine (provided it has been assembled correctly) but tuning is a different story. If you do not feel confident and are not experienced with tuning I would recommend using an experienced tuner.
