Guest TREY260ZTURBO Posted March 13, 2007 Share Posted March 13, 2007 I have a 74 260z with 83 L28ET. I just upgraded to z31 ecu which works fine. I am now trying to upgrad to ford 370cc injectors and z32 MAF. I have the this exact problem that redz31 describes here concerning the pocket romulator. http://www.tangentrix.com/forums/viewtopic.php?t=1027 Everything seems to upload to the rom fine, but I have no fuel relay noise and it doesn't run. I have tried 20 differnent rom images. Any help would be greatly apprecitaed. Quote Link to comment Share on other sites More sharing options...
eec564 Posted March 13, 2007 Share Posted March 13, 2007 Try unhooking the romulator, and taking your engine back to the original injectors and chip. After making sure the engine is running perfectly, plug the romulator back in, with an un-edited rom, exactly the same as what runs fine in your car, on the original chip. If it dosen't run, then your romulator has problems. Next, try editing your injector sizing by around half a pound or something, still using the stock injectors. It won't run well, but shouldn't hurt anything, and it will verify that the editing is doing what it should. Verify the engine runs as your configured it. Then set everything back to stock, with the romulator. If everything has worked so far, now you are ready to swap injectors, and edit the rom. Troubleshooting 101 - only change one thing at a time and test at each step. You'll figure out what works, and exactly what gets you caught up. Hope this helps. Edit: I just read the post you linked to. Tips to check your soldering job: Verify no two pins next to eachother are shorted together. Use a quality meter, I have a 40$ Metex that has proven to be EXTREMELY accurate, reliable, and high quality. Next, test to make sure that each pin on the socket connects to where it should. Using good light, visually trace the circuit paths on the circuit board, and test to make certain the pins connect to the other points on the board they should. If they don't, solder a small jumper wire to make the connection. Be very careful not to solder a wire where it shouldn't be, and always check to make sure you didn't make any connections you didn't mean to. If you need help soldering or seeing small paths on the circuit board, ask for help. Soldering is difficult and there is an art to it.

Guest TREY260ZTURBO Posted March 13, 2007 Share Posted March 13, 2007 I have several other ECU'S (88 n/a, 89 n/a, and 84 turbo) that the car runs on but very rich at idle as you would expect. My original rom was damaged upon removal so I haven't been able to try it. One other wierd thing-If I load a rom from an rb26dett, the fuel relay kicks on and some other noises.

Guest TREY260ZTURBO Posted March 13, 2007 Share Posted March 13, 2007 I checked the soldering job, which I paid a TV shop way too much to do, and the 2 pins on the upper most, right side AND the very top 2 are a dead short. Also, the stipped the hell out of the bottoms screws so I can't look. I'll bet that's it and there are some skulls to crack. Keep in touch... Thanks Quote Link to comment Share on other sites More sharing options...
Guest TREY260ZTURBO Posted March 15, 2007 Share Posted March 15, 2007 I checked my other ECU (Stock) and it has the same shorts. So now I just don't know. Anybody? Thanks so much! Quote Link to comment Share on other sites More sharing options...
Guest TREY260ZTURBO Posted March 16, 2007 Share Posted March 16, 2007 Anybody? please help. I am I doing something wrong? Quote Link to comment Share on other sites More sharing options...
eec564 Posted March 16, 2007 Share Posted March 16, 2007 I'm still thinking. There has to be something wrong with either the romulator or the ECU that's been worked on. Quote Link to comment Share on other sites More sharing options...
Bernardd Posted March 16, 2007 Share Posted March 16, 2007 what year ecu are you using and which binfile? is the key on when you're uploading to the emulator? what size is the binfile you're using? Quote Link to comment Share on other sites More sharing options...
johnc Posted March 16, 2007 Share Posted March 16, 2007 I thought this had something to do with Star Trek, "Captain! The Romulans are charging their Romulator and are ready to attack!" Quote Link to comment Share on other sites More sharing options...
