air flow meter affects mixture
coolant temp sensor affects what?
throttle position sensor affects what?
reason: i have a highly modified motor that runs rich at idle and pings at high rpm.

G'day

Airflow and tps affect acceleration enrichment
Air temp sensor in the airflow meter is only a reference.
Coolant temp is for warmup purposes
Knock sensor is for retarding timing

What mods have you done?

Cheers

didnt you understand?

the ECU controls mixture and timing according to inputs from the AFM, coolant temp sensor, the crank angle sensor in the dizzy, the TPS and the knock sensor

and exactly how "highly modified" is your engine?

my motor has;
30 thou oversize high compression pistons
crank, pistons and rods all balanced
mild 1800 - 4500 rpm cam
larger inlet valves
head flow tested to 300hp
all inlets match ported and polished
custom inlet pipe allowing straight flow from afm to throttle body (battery in boot)
headers
straight through 2.5 inch exhaust
thermo fans instead of clutch fan
egr and isc valves both removed


where can resistors be added to sensors to correct timing and mixture problems???

dont add resistors, the best thing you can do is go for an aftermarket ECU

it itsnt *that* expensive to go to an aftermarket ECU, cheapest option would be megasquirt

EECIV was used in various forms from the early 80's right up to the EL's, so you can pick and choose, but in any case, its gonna require some remapping

megasuirt is a build-it-yourself replacement

easy enough to fit if you've got some electronic smarts

ask this guy for more info

G'day

I'm running mine on megasquirt atm.

By the sounds of it you dont know alot about ecu'as so i think that ms will be out of your reach. However, if you need help and have questions, shoot me a pm.

Cheers
