I usually turn off throttle enrichment when doing a tune. Get the basic map working first before applying correction factors or you can end up going quite mad!

The RB30s dont have a throttle enrichment table to turn off however
Did some more work on this last night, ready for bench test/debug. No time tonight to work on anything, I had three ECUs to work on getting home tonight... each took about an hour!
Anyway it is definately something I've got to play with on the car. You can tell from AFM input if there is a sudden increase in acceleration and can use the last few readings to determine that.
If you detect a sudden increase then discard those AFR readings also.

what kind of mods are required to the knocklite to feed the DLP board?
I'd be keen to get it working as i don't have any form of knock detection on the KA at the moment, only the knocklite with the sensor not mounted in the best location (mounted on the head at no 4 sparkplug end).

take apart the knocklite, take the wire for the led and run that to the dlp input.

the knocklite has an output for the turboxs computer wouldnt we be able to use this output instead of taking apart the unit?

I'll get Pete to check that with a scope when he gets back. He should have his unit back by now. I've finished up all the coding for that and the AFR tuning stuff whilst I was on my ahem... vacation

I can do some testing if you like.
I dont really like my engine so if something goes wrong

That would be great. The latest beta version is up (see other thread)
Havent been able to find RB30 heater hoses today, so got the closest matching thing and see if they fit okay. I'm glad this happened in Adelaide last night and not on the 600km trip earlier that day...

I tried the auto afr and nothing happened?? no cells changed.

if nothing happened, can you check your TPS inputs in NIStune?
The switch should be active and at least 1 volt on the reading from memory. Going to get the hoses put back on the skyline soon and have a go after that

why does it look almost flat in the wot run area?
Posted: Sun Dec 16, 2007 6:22 pm

theres a big drop in this area. it shouldnt be this lean... looks like its going for about 14.7
that is the delay between the wideband data reading and then these values being changed?
what is your target AFR map also which you are using to autotune against?

its really good in that area, 11.5 all the way.
here's the map. rename it a .atb
