Nice looking project - the RB lump makes the best noises.
I think those dips in RPM are exactly the same as Maff has been having.
We've only seen this in on Nissan rev counters, so we're going to have to take a look at what's happening, work out why its happening, and sort out a fix. Hoepfully I'll be able to scope a rev run at the same time as I datalog it, and work out if its just a case of changing the RPM count and/or divider.
Looking at your lambda curve you have a pretty good AFR curve there, 13.x:1 through to 12.x:1 at high boost and RPM
We now have a beta release that should solve the RPM drop out issues, I'll be testing it tonight and then trying to figure out how to write the Instruction manual!

Ah i look forward to the release ;D
Any thoughts on my possessed guage flipping from AFR to Lambda. do you want a vid of it or a dump of the program or it sending back????
It not that much of an issue (when using a laptop) but there is really no point of having it in the car as i cant read the display when driving.
Good point on the AFR flippery...
Can you bung me an email (
[email protected] ) with the serial number and a brief explaination of what its doing (just cut and paste what you've written elsewhere) and I'll get something sorted
