This afternoon I installed my S300S chips in my MY85 S3. i connected the battery after adjusting my 928Motorsports adjustable FPR and it now the car won't start. I check the fuses and relays and then jumpered the fuel pump relay, no change in it's condition. I looked at Porken's recommended requirements prior to the install and the only thing different is that I'm using WR7DC spark plugs vs the recommended WR5DC. I am also using KSM 4 hole injectors rated at 24#. It almost seems like the engine is getting excessive fuel. As it will turnover after removing the jumper until the fuel in the line is exhausted. I was slightly successful at keeping the engine running for about 10 seconds by pulsing the FP on and off as not to flood the system,

Any suggestions in further troubleshooting?

Chip(s) installed backwards?

Note if yes, the chip(s) will be fried.

I did install the LH in reverse prior to see my error. What's the cost to order a new LH only?
