ok does the injector have 12v on one of the pins? the injectors all get power and the ecu switches the ground.
mike Now, with the injector plugged into the harness I got a reading of +12v on the light green signal output wire from the ECU to the injector, ignition ON. While running at idle, the light green signal output wire from the ECU to injector still read +12v w/o any ground time. In other words my injectors are getting proper voltage, but the ECU is not grounding the rear primary when the car is running, hence no firing. |
Sounds like a step in the right direction atleast, Mike. Does the FSM have a good schematic detailing the ECU? Can you pop it out again and look for what you thought had been burned out? You're running the JSPEC ECU, right? I don't remember if there was any difference when we were doing the voltage checks that day in your driveway. How much would it cost you to get your hands on another one?

I have a theory that only half (one of the two mother boards) the ECU is turbo specific. So when I get some extra cash I'm gonna buy an S5 NA ECU and attempt to replace the burnt components. I just hope the processors in the J-spec ECU aren't bad. Maybe I can have two working ECU's. However, in the meantime, I just bought an N370 ECU (YAY! A-spec!) from a guy in GA. He was really cool and is sending me the ECU before he gets payment. So I'll be throwing that in the car ASAP. Thanks Mark! I also ordered the components to build the Paul Stoaks FCD from Jameco yesterday. I think I'm going to avoid the mass-produced FCD for awhile, those things are the devil! BTW, hows the T2 coming along Keith? I must admit that is one sweet car. That car is in such good shape internally. The suspension is incredibly tight for a 14 yr old car. That thing is gonna be badass someday. Not that it isn't already. B) Too bad you moved when you did, the DFW guys are trying to organize a meet at Turner Falls in a few weeks. There are supposed to be like 15-16 2nd gens there. |
Mike (OKIERX-7):
Dude, right now the T2 is just sitting. I haven't had time to mess with it since I moved, which so far has come outta my pocket ($2000). I have some plans as soon as I get that money back from the AF, but until then... I have started putting a plan together, though. A shop my G-pa knows is gonna paint the car for cost of materials and I get to help. I'm going to piece together my own exhaust system (Downpipe, Random Tech Cat, Piping, and Mufflers) and get it welded up. I don't think I'm gonna have time to re-build the engine myself (school's ALREADY started)... so I think I'm going to have it re-built ( https://www.nopistons.com/forums/pub...IR ). Don't know if I have any other options. I was gonna go the JSPEC route, but that would take extra time (installing and fine tuning). Dunno man... Hey your sig says NPR FMIC... did you get another one and have you installed it? I need to pull mine outta storage and work on polishing it. I've been doing some searching and I might get the end-tanks rebuilt so I don't have to do as MUCH hacking to get her in there. Will we see a pressure drop if we're running a small NPR? Mosts posts on these things only mention a drop with the large one :unsure: |

Anyhoo, I believe the pressure drop is something like .5 psi for the S5 turbo, but I'm not sure if its the same for the S4 turbos. I would think it all depends on the shape your turbo is in as well. I've heard from people I sold those to, that increased lag is the most noticeable drawback. An upgraded compressor wheel would solve that pretty quick. I just hope this ECU I bought solves my problems. |
No emissions? You lucky dog! I've got to plan all my mods AROUND emissions.... https://www.nopistons.com/forums/pub...IR#>/angry.png

i think its your ecu too. if its something like an injector driver than you should be able to take it from another ecu and make your work
