Ill set the patch up for a little bit more simple operation (right now its 32x16 function using both ignition tables, one at a time, switching as a function of TP) and send you the details and .bin here tonight.

I wrote a patch to fix this so that the ecu will only use a single 16x16 table at a time, outputting the value to both actual timing advance and consult. But of course, it is not something that can be done without reprogramming the nistune board, and would need to be done to each code version sepera...

A better approach to understand oem boost control would be to start with analyzing the boost control hardware itself. Any sort of dynamic boost control is going to be done using one of two methods, in combination with the appropriate hardware for that method. The two methods that could be used are P...

Yeah I know how those little cars can grow on you, the 121 (which I think is a ford festiva over here) has some good body lines. Ive been keeping an eye out for an AWD subaru justy myself (if I cant find a cheap impreza first). My daily is the corolla ae86 hatch which I drive year round even in the ...

Haha, I just searched and found what a Mazda 121 is, not exactly what I was thinking... We have one of those sitting in the pen at the shop, reminds of the March SuperTurbo. Anyways, I was thinking it was a rwd layout. What you would need to do is find a distributor/CAS that is the mitsubishi optica...

Hey PL, I havent yet made much progress on that project yet. I still need to buy a sr20de or sr20det distributor/CAS as that seems to be the best fit. These units are overpriced, and the rwd sr20de distributors which might be cheaper are hard to find in the US. I also need to machine an adapter, her...

Nothing like breaking in the new shop eh, a good way to find out what tools you need to add to your list :) Can never have enough tools! I bet that clutch was fun :), Ive never worked on a P11, but I know P10 USDM Infiniti G20 is packed tight, done a couple jdm engine swaps on those and they are a m...

Here are the stock latency timings for the 2nd generation 1995 DSM awd turbo injectors (450cc) from the mitsubishi ecu rom. As far as anyone knows in the DSM community, scaling is done to this battery voltage table alone to compensate for alternate injector opening time. Volts/ uS 18.70 / 495 16.35 ...

uS (microseconds) is the most accurate way to display injector opening time, and it would provide the most compatibility to information provided in any injector datasheet. The only time it would not be, would be if the injector data you have was written specifically for the nissan hex/dec value whic...

That sounds promising. The idleMAFco pin should have around 3 volts on it without a thermistor connected. You will need to put a potentiometer between sensor ground and the idleMAFco pin, then once you get the Nistune board on it I can give you a handful of RAM locations to trace in order to find it...

Hmm, well, what did the circuit for that "MAF idle CO" look like leading to the ADC? Any sort of bias resistors included for a thermistor perhaps? I have never heard of that, I wouldnt know what it does. Did you get a chance to stick an emulator on it yet? I setup a VE routine with room for future I...

I would rather not sacrifice the o2 sensor ADC channel to do this, but yes it could be done that way. This wouldnt be very easy though as the o2 value is probably used in a variety of different locations for closed loop fuel control and the patching would be extensive. Also it would be counter-produ...

Basically what I would want to try first is to skip the idle routine entirely. If that doesnt work, rework the beginning of the routine to set some of the idle control bits/bytes to static values, and then return from the routine. If it doesnt work first try, fiddle with the bit settings a little mo...

They look valid, I wasnt so sure at first though. Ram byte 0045 confirms.

They are coolant temp based, not RPM

The code doesnt seem to use an 8 bit TPS adc count, that one provided is the msb of the 10 bit count, so it will only go as high as &H3F EDIT: I mean as word it will only as high as &H03FF, the MSB for this wont be appropriate for display, not unless you split it across two bytes. &H0043 might be a ...
