Product Information

Based on a stock 2000+ 3400 swap into a 5 speed Fiero, with the 1227730 ECM.   All manual transmission setups should be a plug and play deal, while the automatic may need some tweaks to fine tune.  We have done a couple auto trans setups but mostly manual trans.  2000+ injectors and 55 PSI fuel pressure required.

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. Please put this into the Additional Information field.

Please be sure to tell us if your dash is digital, so that we can use the correct ALDL code.


These adapters must be installed onto the stock memcal (chip), and then inserted into the computer itself. Be sure that the chip on the adapter is across from the chip on the stock memcal. The stock chip should have a silver sticker over it.
