3400 Swap Chip

Product Information

Based on a stock 2000+ 3400 swap into a 5 speed Fiero, with the 1227730 ECM.  Even without dyno tuning, this chip is still more complete than the competition.  Once the 3400 tuning is 100% and feedback from other platforms is accounted for, these will be finalized.  All manual transmission setups should be a plug and play deal, while the automatic will possibly need some tweaks to fine tune.  There were no issues on the test vehicle once the street tuning was done, and this accounts for both warm and cold (40 degree outside temp) start, idle, cruise, wide open throttle, decel, and coming to a stop.  You must have the 2000+ injectors and 55 PSI fuel pressure regulator that was standard on all 2000+ 3400 engines.

Custom tuning is available for modified 3400 engines.  Vehicle either needs to be here, or you will need to supply feedback along with a datalog (scan tool required) and have a chip burner to write the chip yourself.  No shipping of chips back and forth will be done for custom tuning purposes.

4 Letter chip code for your stock chip is required. This can be found on the stock chip, printed on a silver sticker with 4 numbers below it. 

1990 and older Digital Dash owners cannot use this chip.
