OK Chris, you're going to have to explain this one to me a little more. You have a 1995 Elantra with a 1G 6-bolt, right? What "stock tach adapter" did you use?...
Hi guys. I've seen that eprom programmer on ebay and i would like to know if you guys think it's worth to buy. Have anybody ever used one of those programers? ...
I bought something similar on eBay but from these guys: http://www.sivava.com/ . The instructions were less than clear but it was working fine. Christian...
im using the adapter that came on the elantra. not really sure why it was there. perhaps for the stock ecu. mine originally didnt have a tach, but i bought a...
for starters the car wont start. the main problem i am having is that the mpfi relay is not applying power to pins 102 and 107. the relay has power. this has...
Hello once again all. I've been lurking and searching lately for a start or solution on how to extend my rpm maps in my 1g ecu. A few years ago Kyle helped me...
Thanks a ton! I am looking at it really quick but the way I read it you are simply making more space for extra timing columns? Is this correct? So the ecu just...
... I guess a lot depends on what year that tach cluster is, and what polarity tach pulses it is expecting. The 1990 DSM's had HIGH pulses, and the 1991-1994's...

Not so fast, Dan. It's a little more complex. You have to tell the ecu how many columns there are, and you have to dictate how many rpms there are between...
I've searched the archives, and haven't found any solutions to what I'm seeing. I recently redid the fuel system on a GVR4. I've set the chip up for Denso...
... Yes, I was thinking that this would probably work. As long as you run a wire DIRECTLY from the tach drive of the transistor to the ECU it should work fine....
... Drew, How long have you driven it at high cruise? Are you sure the HIGH TRIM just hasn't settled in yet? I'll have to look at Christian's disassembly. I...
Sorry to dredge this old post up guys, but does anyone know/have the code that came in the JDM MD150427 ECU? I have a MINT non-EPROM one here, with the number...
Thanks Steve. I was hoping that wasn't the case. Those E769 maps are pretty crazy.I can't see anyone in this country running it without race gas. :( Jeff O. ...
Thanks again. What is the change for FFC3 for again? I now see that DC06 and DC21 tell the ecu how many columns I have. Also I assume that I would not...
The trickiest bit is to figure out a more accurate reading of mph. I do this by first finding out which gear the car is on ( by comparing the inaccurate speed...
I recently installed zeitronix wideband on my gvr4, so I tweaked my 2G MAF ( 609 ) compensation curve to match the wideband reading. My result showed that the...
FFC3 is the start of the section of code that sets the scale and size of the rpm columns. Essentially there are 28 (1C) columns on a stock timing map in 250...
First, hi all. I was just linked to this place and it looks promising. About myself, I own a '93 TSI AWD and my job is designing printed circuit boards....
Hello! Any suggestions where to get a data logger and data cable for Evo 1-3? Evo 4 up uses Mitsulogger/Evoscan and tactrix cable and laptop. Can this work...
Alvin, I don't thing any of those have an OBDII port. Like our 1G/GVR-4 cars, they probably only have the ADLD diagnostic port, so you have nowhere to attach...
Since my last post here we've got the ECU logging unclipped airflow and load. I've got it changing the octane number to map switch between low and high octane....
If you'll forgive me spouting off on a protocol I'm not familiar with, I am used to SCSI/fibre/SAS etc. protocols that are used for computer storage. Where...
Thanks Carl. The info on the MUT protocol came from the DSMs :) To get into it there is a 5 baud signal then some init codes. Then a byte is sent from the...
