I hope someone can shed some light on this. It is a car I was asked to look at at a shop - A Hyundai Elantra with a 4G63T swap with wireloom and computer. It...
I had this problem with a Colt swap a few years ago, turned out to be a connector at the ECU. One wire was not connecting right and it was stuck at 5degs at...
Wreckleford: This is nominally due to a miss-wire. The ECU thinks that the key is in the "start" position. Check the wiring on our MPI relay, or verify that...
Has anyone tried using the 27SF512 in one of these yet? people claim it as the replacement for the no longer available 29c256, my buddy had a 29c256 we used...
Please could someone let me know if this is the right code or if I'm way off here. I'd like to get this manifold working since it's on the car. :) Thanks ... ...
Would anyone happen to know what ohms that the pins should read? I dont see anything wrong with it however I am a newbie to all of this and was hopping to...
well, im not trying 27C chips ;-) trying 27SF chips! lol, these are electronically erasable, cheaper, and 2x the capacity... ive heard similar things though,...
Jeff O. What I am talking about is a ECU computer for a Dodge colt. I unpluged it and wanted to know if I can check the pins that the wiring plugs in to!...
1.8l, 2.0l?? The Dodge Colt ECU's I've seen are almost identical to the non-Turbo DSM ECU's, and the pinouts are very similar to a turbo ECU, except without...
Jeff O. Thanks for the input. I am new to all of this and I am trying to learn about them. I have a 1.5 engine non turbo. But what I am mainly working on it...
Thank you Jeff, this works great. It opens uder the stutter box once I build over 5psi but I can live with that.:) Thanks once again Jeff for all the info...
I've just got my cyclone intake on but can't seem to get it to activate. I'm using the "purge" button under test on the mmcd to activate the PCS solenoid. I...
That's why I write my stutterbox code with a check to see if the car is moving first, to avoid opening the Cyclone secondaries when you are launching. You just...
I'd have to check the code again, but I'm fairly sure that when you write new code to go into the Purge Solenoid block of code, the Purge Test no longer works....
Hi guys, my friend that owns a '95 GST has a problem that makes us going nuts. When he tries to datalog the TPS (throttle position) always get 0% value,...
Nobody has any idea of why can the datalogger show 0% throttle position even if there's good signal on the ecu pin 84 and 5v on pin 81? Jeff, any help? ... at...
... In summary, the problem is that you are getting a reading of 0V from the ECU even when 5V is applied. Swapping the ECU with another one that is known to...
Hey thanks for the info. I see it will not be easy to diagnose. I'll tell him to try that and see. I was thinking the same thing about a possible 2nd fried...
... I'm pretty sure that shouldn't be an issue. The ECU does have its own signal tap for the TPS (as you know) and doesn't rely on a CC unit being in place....
Ok, i have news. My ecu is working well. At least i tested it with the datalogger and it reads TPS correctly. I had an idea and i tested voltage on every ecu...
... doesn't really matter, probably ground differences ... Yours is actually open and floating, his is closed. Just means the reed switch in your odometer is...
