Default anyone use the fast 302000?

Anyone use the Fast 302000 system? Most likely going to throw out my stock ecm and replace with this system. Anything I would need besides a different distributor? Will all my guages still work? ...my harness is most likely causing my problems and it cause my dynamic efi to catch on fire - there is a short somewhere.

I would rather just get rid of the harness and replace with the fast system - would you recommend buying the sensor pack that it comes with or would mine be ok? Do i need any adapters from the harness to the sensors since my car is a 91?
...looking to buy this asap

Thanks!!

Interesting and the price is good but I think you would probably lose gauges?

You would probably want to get the sensor pack and run it piggy backed.
It would run the engine entirely, but leave the stock sensors and what not connected to the stock ECU, then your gauges will still work.

You should note that while that is a simple to install system it is a very basic system without much expandability or tuning control compared to typical standalone systems.

That's what I was thinking just use my stock ecm and then the fast system and have the whole harness in the fast system hooked up to the sensors leaving the ecm connected and just disconnecting whatever the fast harness hooks up to....but if I hooked the fast system up to the stock sensors would I lose my digital dash? I guess my question is what part controls the digital dash?

Also talking to Fast they said this system would be best for me and this is all I would need. I do not plan on going naturally aspirated and I need my car to run already! Does this sound right to you? I know minimal when it comes to this ecm ccm standalone crap


thanks

the 3 analog gauges use their own sensor, pretty much everything displayed in the center display needs input from the ECU.

You can't share most temp sensors between 2 ECU's, you may want to add additional air & clt temp sensors..
