I would not advise altering the second table unless you want to increase/decrease the dwell time based on RPM The second dwell/RPM table is to compensate for the ECU pulses being generated from the RPM signal. As the RPMs increase, the pusle generator in the ECU has shorter pulses. This RPM/dwell t...

so no matter what I do it seems my idle gets very rich on really hot days(like 9-8afr's) I adjust the k-constant and for a minute it stays at 14afr. tuen the car off or come back from deceleration and it's back to super rich again. I can cruze at 14 afr but it's the idle when iam in traffic that is ...

actually I have the ones with the heat snk on them. no external ignitor needed(like on s2 rb25)

kick ass matt. with that dwell adjustment I made 350whp at 15psi and stupid rich at 9afr. will include the map I used later.

but wait. aren't I supposed to be between 3-4 ms for optimal firing?? and in that chart above do I copy the red line or the purple line?

is this the right way to go about it??

has anyone else actually ran meth and nistune??

so which table do i adjust now again?? the duty cycle or dwell time??

so if i put 3.0-4.0 across the table for the dwell time, would that do it??

yes iam also hungry for this to work. so if it works for the r32 this will work with the r33 with vvti right??

so does this have the hickups that are usually associated with the lightning maf blowthrough?? like stalling on deceleration, etc??

so there seems to be mixed reviews on this setup. I need testimony/pics of being mounted for actuall people using this maf and your experience please?? I want to run a blow through setup, hopefully yield some more power/efficiency. iam running a z32tt maf on my rb25det engine. in the usuall pre turb...

so iam looking at this setup for my rb25det(s2). anymore complaint/praises for this maf??

update on this??
