I have put a 455 olds in in a boat and put gm tbi 1227747 with a asdu 9567 chip. Will this be ok as it was off a 350 chevy. Timing module has to be off 454 chevy as 220 tbi. steve

I think this thread will help you find a better choice than ASDU 9567: http://www.gearhead-efi.com/Fuel-Inj...Information-42
I think the ATPZ 87 R-V Truck 7.4TBI 4 speed manual with 4.10 or 4.56 gears.BIN would be a better option than ASDU 9567, if you can find an early 7.4 liter 670 CFM throttle body with 80 lb injectors.

thanks for reply, that is for 454 chevy. If anybody knows where I can find one let me know. FYI that 454 timing module, new gm 1613231 is on ebay for $50.00 steve
Some of the early TBI 454 engines did not use a knock sensor. It might be possible to run a 455 without a knock sensor? There is the option of adding a knock sensor after getting the 455 running?Quote:

Do you know someone that could help me with that chip. Can someone flash a chip? Again this is all new to me. thanks steve
I might be able to help with a starter chip. A starter chip is basically a good guess for fuel and spark tables for a non stock or modified engine. A starter chip usually gets the engine running, a very relative term. A starter chip will usually get things in the ballpark, but not down on the playing field! Sometimes a starter chip will only get to the parking lot of the ballpark, which kinda sucks to hear the crowd roaring but can's see what's happening. Typically the less stock an engine is, the less likely the starter chip will be on the playing field of the ballpark.
One proven method to get on the playing field with a chip is to data log, a method that clearly shows why the crowd is roaring! I suppose it would be cool get an engine roaring too!
Send me a private message, maybe we can figure things out for a starter chip.
