upgraded from 9266 to latest version

so upgraded from 9266 because it locked me out, now when i view log files in the log viewer the afr trace is just flat at the bottom of the logger window. guessing you can't view old logs in new version which kind of sucks because i want to view old data logs. all the other data is graphed fine but ...

would be nice to see inlet air temp readings same as ambient. i.e sensor left hanging on machine. but that has to be one of the most powerful rb20det ever. i put a post on sau previously because these engine have always dissapointed me, never seen one crack 300rwkw in person. a few people posted aro...

i know this is an old post, but for anyone else in future, yes that is correct.

the msd instructions state that the original ignition module should remain to trigger the new cdi module.

not direct from ecu.

mallory would be similar deal.

have you got the standard narrow band oxygen sensor plugged in, it shows 0 volts on that channel in the software, most likely the reason the cruise mixtures are mid 13's instead of approx 14.7:1, unless you unplugged it for the log? accel enrich is handled by the standard airflow meter overshoot, ra...

combination of boost spike and once the engine is past the peak of maximum volumetric efficiency airflow will fall.

finally got around to fitting the bosch recirc bov this weekend. got the high pressure bosch valve from saab (Saab dealer #4441895) for $75 trade. audi wanted around $110, and these were the only two i could confirm were the high boost versions via the part numbers. its all plumbed but the vac line,...

for rb20/rb25 series 1 afm (4wire type) it should go

1 no connection
2 signal output (0-5v)
3 earth for supply voltage
4 earth for signal wire
5 +12v supply voltage

most of these ecus have an "afterstart enrichment" map, that is applied for a minute or so after startup, the amount does reduce with temperature, but it is applied at all engine temps after starting. also some nissans vent the fuel pressure regulator to atmosphere for increase in fuel pre...

the auto z32 roms need a speed input of 8km/h+ IIRC.

the manual roms do not need speed input and should work without changing that value, just make sure the tps input signal represent more then idle voltage and the neutral position sensor input is not on.

Sorry, In continuation with what I was saying earlier, what I think is happening in reality, is the Z32 afm reads slightly more voltage at low airflow input, i.e idle and cruise and when you get to the higher voltage 4-5V, it is putting out less voltage increase for more airflow increase. Well I kno...

Hey Matt, Sorry to bump an old thread, but i'll try to keep similar topics in the same thread. Back to what I asked originally in this thread some time ago, have you since found out if the later model nissan ecu feed the AFM 0-5v signal to the a/d convertor directly or is it actually protected from ...

all he should have to do, is drop the k value and it should trim up rather nice, if he didn't do injectors at the same time. did he fit the 390ohm resistor across the pins? nothing wrong with your guide at all. something else is wrong if the k value has no effect i think. should have some more resul...

Matt,

What does Dynowog have to typically do when he fits the Z32 afm's, scale the k up or down?
