M30 b34 N/A Stock microsquirt help

Post by cprojects »

So long time listener first time caller. Was wondering if anyone had a good stock ignition and VE table?
Currently have ls coils running wasted spark on 3 channels 2 channel batch fire. I can get a idle at like 700-800 at around 40kpa engine shakes a little bit just seeing if anyone would mind me looking at a N/A tune.

No help, but I like your first line.

Just as a reference :) ignition might work out of the box, but fuel does usually not work like that

Thanks for the maps I’m having a heat soak problem my IAT goes to like 140 at idle at light and goes really lean…. Also after highway trip I’m randomly under low kpa start misfiring almost stuttering before I’m creasing revs clears it out…….

What kind of afr you running

I have the same issue regarding the IAT, it's always gonna happen for me, because the sensor is on top of the valve cover. I'm going to go turbo in a short while, that's why I haven't bothered on relocating it.
As far as AFRs, this is what I used to auto tune the engine.

Appreciate the response I’m working on my mat/clt to combat the heat soak after 25 minutes of drive I have to adjust the whole map haha mind if I look at your msq? I’m new to MicroSquirt but I have a turbo waiting to go on I have 440cc injectors in it right now ls coils kinda drivable hahah. I get the heat soak also I’m having this weird voltage pulse in tuner on the gauges I measure at the battery and it solid at the controller solid fuse block solid.
