We have A/T car with manual gearbox. Works fine, all A/T stuff is removed, but wiring harness still has A/T controller connector. How did you actually re-scale your injectors? What values you are changed from ROM? All load dependent tables must be rescale. missing v-signal makes your engine run abou...

623 bin: There is throttle position tables for idle/pt/wot transition. I have no idea where is rpm axis data for those tables... But rpm's are about 1800, 2000, 2400, ???? for idle-pt and 2000, 2400, 3200, ???? for pt-wot. idle-pt 4x1 table, 0xD53C pt-wot 4x1 table, 0xD540 What MAF you are using? MA...

I believe this K value should be used as both a tuning factor for adjustment of injector size and engine size to attempt to maintain an ideal VE correction factor of 128 for the part throttle tables. I think such same way: D5 and D6 are 8bit load values, D5 filtered and D6 raw, but only 8bit. So, m...

WOT acceleration problems :? M50B25TU, 240/240 cams, open loop, rest stock. Is there somewhere positive deltaRPM fuel correction factor? AFR is very good when engine is under max load and constant rpm, but rapid acceleration at high load goes very lean. Error is multiplied as higher is rate of accel...

WOT tables was blocked by some faults or some special conditions. I can't remember, but maybe vehicle speed sensor? cam sensor? I don't know why, but something discrepancy happened.

I never found RPM axis data for idle/pt/wot tables, i think it is shared for multiple tables and it is somewhere close of those threshold tables. RPM's for those thresholds in my XDF was purely found by testing and tracing. They are not very accurate. I did take a break in playing with this device, ...

Direct copy from 80196 user's manual A/D section:
"11.0 A/D CONVERTER
Analog Inputs to the 80C196KB System are handled
by the A/D converter System. As shown in Figure
11-4, the converter system has an 8 channel multiplexer,
a sample-and-hold, and a 10 bit successive approximation
A/D converter. Conversions can be performed
on one of eight channels, the inputs of which share pins
with port 0. A conversion can be done in as little as 91
state times.
Conversions are started by loading the AD_COMMAND
register at location 02H with the channel number.
The conversion can be started immediately by setting
the GO bit to a one. If it is cleared the conversion
will start when the HSO unit triggers it. The A/D command
register must be written to for each conversion,
even if the HSO is used as the trigger. The result of
the conversion is read in the ADÃRESULT(High)
and AD_RESULT(Low) registers. The AD_RESULT(
High) contains the most significant eight bits of
the conversion. The AD_RESULT(Low) register contains
the remaining two bits and the A/D channel number
and A/D status. The format for the AD_COMMAND
register is shown in Figure 11-1. In Window
15, reading the AD_COMMAND register will read
the last command written. Writing to the AD_RESULT
register will write a value into the result register."
02H:
BIT FUNCTION
0 Channel selection (+1)
1 Channel selection (+2)
2 Channel selection (+4)
3 GO-bit (when written to "1" conversion will start asap)
4 X
5 X
6 Least significant result bit
7 Second least significant result bit
By reading 02H is used to check ADC status and last used channel. Bit 3 will clear to "0" automatically, when conversion is finished, so, when reading 02H and bit 3 is "1" it means AD conversion is running, converter is busy.

I believe this is simply the raw 256 bit values from the A2D converter. I get that the A2D is 10bit and would then have to convert into 8bit somewhere in the code, that would simply be the 0-1023 converted to 0-255. The A2D works from 0-5v, with 255 values available that's 0.019531V/value. The sens...

I think that delta load attenuation is used for tune acceleration enrichment sensitivity and scaling load change rate (indirectly throttle opening rate) to enrichment. I can imagine that is comparable to acceleration pump pivot ratio in traditional carb system. Still i don't know what that other del...
