need info about sr20 throttle enrich tables
Posted: Fri Jul 09, 2010 7:21 pm
Can anyone fill me in on how the throttle enrich works on a s13 sr20det ecu, unfortunately the documentaion doesn't seem to cover half the tables that I see in my list.
Specifically I would like to know:
Q offset rpm... no idea what this is?
Increase Fuel... it seems that 'mV' is a function of 'value'?? what 'value' is it reading, and what 'mV' is it??
If its refering to tps volts then surely it would make more sense to have the mV on the x axis...?
Throttle enrich... it is all zero except below 20deg?
throttle enrich, fast movement... what does this table do?
tps enrichment trigger... its all set to max, 255. what does this table do?
throttle open offset... again shouldn't the volts be on the x axis, also, what does this table do?
decel loss ratio... ???
decel loss rpm...???
decel loss temp...???
I've just changed injectors to nismo 555's using the injector change function. The car drives amazingly like factory after the change, only a tiny tweak to the latency needed to have the afrs 99% as they were with the factory map. The only difference is the afr dives to below 10:1 when ever I step on the throttle, it used to only go down to about 12-13:1 with the factory injectors and map.
