Bryan, ... That is correct and promotes some interesting thoughts. Advanced 5 deg the HKS 264 intake opens nominally at 27 BTDC, a little bit earlier than the...
... I converted the Timing and Fuel maps so they can be easily viewed. You can check them out here: http://home.dejazzd.com/ceddy/timing.htm and here: ...
I am running a chip I got from my mate, I have an 88 JDM, his is an EVO 0 JDM. The chip has a launch controller written into it, and is based on E952. When the...
... EVO 0 ... on E952. ... it in ... It could be that the code thinks you aren't moving (no VSS), so it is still in launch control mode. Or, it could be that...
I did have a VSS error code stored on the ecu a while ago come to think of it. How can I check if the ecu is detecting the vehicle moving or not, is there an...
could it be that you have your clutch switch wired in backwards? I know I and lots of others have made that simple mistake when wiring in the clutch switch...
hello everyone from mexico since importing an eprom ecu is costly , i took a quick look at microporcessor pinout and I think that soldering an eprom to my...
To finish this part of the thread - I finally setted on HKS 264/272 cam timings of +5 In /-6 Exh with a 1000rpm idle, 10" vacuum. Idle sounds lumpy like it is...
Andrew, I'm sure that I have *something* to do with that chip, so I'll tell you what I can: 1) The JDM speed sensor is at address L0xC4, not C6. So, you can...
To my knowledge, there is only one company that converts NON-EPROM boards to EPROM, G-Force, and the cost is $600-$700. Hardly worth it. You can't just...
couldnt a small daughter board be fabricated with the necessary circuits to operate an eprom. run the correct addressing lines to the processor and cut or...
... It can be done and I've done it, just not in a reliable way for very cheap. The hard part is getting ahold of real adapters that allow you to go from...
That is very helpfull, thanks Jeff. If you would like, I can give you the ROM I have taken a dump of it, it has two bits of code in the beginning, the second...
I had never realized that Hondas use daughter boards. It can't be TOO expensive, can it, or wouldn't they just be running AEMs or the like, wouldn't they? The...
If the code starts with 96 C4 then you have the simple, speed sensor- based 2-step that I mentioned. The reed switch is on the backside of the speedometer, so...
Hi Andrew, Im guessing you took a copy of the chip I sent up to Kris. Im running a similar chip on my 1989, and there are a few around running on 1989s so...
... What cam gears are you using, out of curiousity? I know some brands are labeled backwards, and want to make sure there is no mix up as to what is advance...
Im considering implementing a methanol control system into my ecu using one of the pwm solenoid outputs but im not sure how to set it up hardware wise. i dont...
i used a set of fidanzas on a set of fpcam2s (supposed to be similar to the hks272s). with stock gears or the fidanzas at 0, the car idled like crap, something...
Intercooler too small. went from a 2-120 core to the kinetic race core and my VE went up big. duty cycles at the same boost increased from 76% to 85% on...
I wrote some code for selectable maps that uses the resistors at 129 and 130 to determine which map to use. I check the resistors using; 87 55 04 xx - for r129...
... Seth, I'd suggest looking at the code starting at ea21 where the real config resistors get read from port 0x07. You can then set 0x55 and 0x56 how you want...
I've done similar things Seth, and as Steve said, I prefer to just read and mask 07 instead of 55 and 56. I believe the only place that those addresses are...
