Hi.

Just wondering if someone is able to help me out getting my car running on my ms2.

Car is boosted and has 850cc injectors and its making me have big issues getting it started and idling.

If you have a second car, and you want a hand, how about you give me a lift from the track and Ill have a look with you?

If you tell me the specs of the engine, in detail, and ms2 firmware version, I should be able to send you a tune that will start, idle and be a good base to tune from.

Ahh, the DIYPNP2 right? I think it has 3.1.2 firmware. Can you email me the tune you are running right now, and I will send you back an adjusted tune that should start the car. Just the MSQ (tune) file.

Just looked through the tune, and change the Reqfuel to 3.6 (from 12.7) with those large injectors. It would be dumping too much fuel and flooding it I would say.

Without more info on what specifically is stopping it from starting, I can't suggest anything else. A log and more descriptions on the behaviour - ie does it catch and stall out immediately or does it not even fail to start? Have you checked sparks? Is fuel being sent out the injectors? Is the timing close enough to start (CAS adj) ??

Have tried changing the req fuel to that already after the change is made the car doesn't start at all.

Spark plugs were flooded, so I gave them a clean and there fine now.

Does it spark? Have you tested to confirm? If your are 100% sure spark is working, then you'll need to get a timing light to confirm that CAS is correctly timed along with the configurations Trigger Angle/Offset deg... I think in the tune it is set to 4 deg, but that might be wrong depending on the angle of your CAS etc. It won't start if that's way off.

Also, when you say it "won't start" I'm assuming it is turning over, and there is not even a sign of ignition or any spark lighting the fuel.... which tends to suggest either no spark or spark is so out of timing that it can't combust.

Another trick I've found works is to have someone turn the key, and with the CAS bolt loose, turn it slowly until it catches, and then you can hold it in a rough position whilst the engine kicks over, starts, idles and then hopefully stays running - when so, you can then use timing light to confirm timing and adjust.

As always, come back with lots of details and information so that we can review and provide advice.
