Are all 914 computers the same?
Will a 76/2.0 run as well with a 74/2.0 computer? Will a l/jet car run with a computer from a d/jet car and vise versa? Will a 1.7 run with a 2.0 computer and vise versa? Inquiring minds want to know. JT |

While the 75/76 ECU will run a 73/74, it'll be really lean. I would think it would also be a mismatch the other way around, as well. There are 2 different 1.7 ECU (maybe more), and they might run a 2 litre, but they're supposed to be matched to the throttle switch and MPS, so they might not. L-jet uses both a different ECU and a different plug, and it not only can't be plugged in, but it wouldn't run the system because it operates in a completely different way (and vice versa). The Cap'n

76 with a miss that only happens every 1-2 miles. .25 sec cycle.
Checked all the obvious stuff, twice. Changed to a ecu from a 74 , problem gone. Now I seem to be down a bit on power and the engine isnt as "snappy". We adjusted the f/a mixand once again check all else, still down on power. Shoot ,now I need to find a 76 ecu (IMG:http://www.914world.com/bbs2/html/emoticons/bs.gif) Unless someone knows a remedy (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) S'cuse me while I go drink.

If I were a betting man (which I am) I bet a 75 2.0 ECU would be the same as a 76.
I'll keep my eyes on the look out JT, I have a few ECU's all d-jet but not sure what they are out of. Luke D |

Oh, that reminds me, I know where a 75 2.0 is sitting all taken apart (my first love that I sold 6 years ago) Car turned up in Clovis from valencia 6 years later completly trashed I might add!! I have the guys number, he might sell it to you cheep, seeing is he wants $400.00 for the entire car anyway.

1.7's are all basically the same
1.7/2.0L 73 ECUs are the same but the 2.0L uses a special MPS 2.0L 74,75,76 are basically the same and use the same MPS (IMG:http://www.914world.com/bbs2/html/emoticons/tongue.gif) |

No over run circut on the 74 ecu,also one less
speed control circut. Is this why the car seems to be down on power? JT |
