I have been looking at the schematic and the board lay out and my head is bashed, lol. While looking at this, I think I may have found the reason why EGT2 reads about 200 degrees out
. I wired it as per the build procedure, lol, its not according to the schematic. The build procedures are screwd up. I think the schematic is screwed up as well:D There is no contiuity with anything LMFAO
Firstly I need to work out how im going to get round the connectivity, as im running out of useble pins
. I have a 'cunning plan' to get round that, but for now, can anyone confirm the following ADC channels and which are free for what type of input. Please be gentle, im only a novice where electronics is concerned
ch0 opamp U13D JP14-1/2 (pressure transducer? why +ve and -ve?) Unassigned?
ch1 opamp U13A JP9-1/2 (pressure transducer? why +ve and -ve?) Unassigned?
ch2 JP16-4 or opamp U17B (digital or 0-5v?) Unasigned?
ch3 EGT2 (assigned)
ch4 EGT1 (assigned)
ch5 opamp U13B or JP19-1. EC18-16, (assigned digital in) for ALS/ Shift cut with pull up resistor.
ch6 JP11-1 (not assigned). EC18-6, but EC pin used for DPAK FEF, onboard wiring removed. (thermistor, digital or 0-5v input?) see schematic, pull up resistors installed, why?)
ch7 JP11-2 (not assigned). EC18-12, but EC pin used for DPAK FET, onboard wiring removed. (thermistor, digital or 0-5v input?) see schematic, pull up resistors installed, why?)
Secondary VR is not as of yet connected to any EC pin, on another note, the shcematic says to remove resistor R59 when proprietary Audi triger installed. Where is this? cannot find it anywhere. Is this something I still need to do? what about R58?
Also on schematic it shows analog in channels 7 and 8 (is the schematic screwed up? should this not be channels 6 and 7?) to have a 5 volt pull up intsalled for thermistors, is this correct? I have not physicaly checked the board yet to see if they are indeed installed.
I will also post this on the wiki, but its taken me 3 hours to work this lot out and post so it can wait till tomorrow, now, lol check the post time
. But if anyone can shed some light
