At some point, my motor (1974 2.0L) will need a rebuild. I'm not going to go the /6 conversion on this car. If I rebuild the motor to a 2056 or 2270 displacement, can I still use the FI system (D-jet)? Or is there some spot in here where it is better to switch to carbs? Or if I wanted to have FI then switching to L-Jet instead?
Happy to do some reading if you have it... (IMG:style_emoticons/default/chowtime.gif) |

Anyone know if the chip in the stock 914 ecu is soldered in?
Anyone had a look at the content on the chip? Shouldn't be that hard to change the fuel table...I have mapped VW Digifant earlier, and the 914 ecu cant be any harder? |

Shouldn't be that hard to change the fuel table...I have mapped VW Digifant earlier, and the 914 ecu cant be any harder? The 914 fuel injection box is not really a computer. The D-Jet is a bunch of 1960s era big assed transistors. The L-Jet is a little more refined, but there is no real "processor" and there is no such thing as a programmed fuel map. It has a bunch of transistors, resistors, and capacitors that control the fuel map. Changing the fuel map involves replacing resistors to change the mixture curve. Welcome to the 1970s.
