I have a 94 sentra ser with an avenir swap and i cant get the motor to do anything i want it to. I have 3 ecus that im trying and nothing is working. its running rich *** the 370s on both the bb det ecu and avenir ecu and wont rev past 3500. on the stock de injectors it wont run with the bb ecu but runs with the avenir ecu but leans out. Im using both a factory de maf and a s13 ka24e single cam maf. the only thing that works is de injectors de maf with de computer. any suggestions?

you may have to use a bluebird or avenir maf! also check for boost leaks!

You should probably just send your factory ecu to calum and have him program it for the sensors and injectors you have. Stop trying to make something work in a way it wasn't designed to. If you haven't upgraded your fuel pump you need to. You also need to be absolutley sure your maf is wired correctly, a lot of people have had problems. The 300zx maf sensor seems to be the most common. I found mine on a j30 for free :) There are lots of diagrams on how to wire them up and there are lots of bin files for them.

I have a 94 with an avenir swap. When I was first looking into it calum wasn't messing with 94 ecus because they were different that one year. He does work on them now. I had to find a pre 94 one and send it to him. It was plug in play. I found a bin file that had my setup, 300zx maf, 370cc, 4 bar fuel pressure.

Don't give up, it'll be worth it in the end.

sounds like bad maf/wiring..turn the key and test the wires with a dvm

yeah check them wires the fatter of the 2 orange wires is the 12v the white is ground and the other is signal wire

94 SE-R's suck when it comes to doing swaps. well that is in my opinion having owned all 4 B13 body years

From what i see calum got more then he can handle right now. im running the stock maf and its still not working with the bb det ecu

humm is there that big of a difference between the bb maf and de maf? oh and i forgot to say that my cousin has a turbo de and the bb ecu that im having all tthe problems with runs his car. his is a 92 ser.wtf?

Run de ecu with de maf on 370 injectors. Ran mine like that til I upgraded ecu, fuel pump, and fpr. I was probably runnin rich but it ran and I didn't run it past 7psi. If your gonna run jdm ecu run jdm maf. It didn't work for me though.

Use your DE MAF, and DE ECU 370cc injectors, and get yourself a SAFC2, have it tuned have fun.

OR

Send your DE ECU to Calum and get it programed for you setup. Do you have a Walbro 255lph fuel pump?

thats a negitive on the fuel pump and i thought calum stopped doing ecus or took a break or something?
