Just now I added some idle stabilization retard, tomorrow I'll find out if that band-aid works. Not much, it seems ECU will not use idle stabilization retard at the same time as its holding the AAC open. But as soon as AAC drops to 20-30% idle stabilization retard kicks in. In summary it still high...

I have not received any codes for knocking with the knock DTC marked.
The KS is in the valley under the manifold. I guess I should have built a sub-harness so I could unplug it for diagnostic.

I did try a conservative nearly flat map with no cruise advance and it still pulled timing...

I like the the startup guide! Reviewing it was useful but I would like the option to not see it every time I launch the software. On the main timing and fuel maps the buttons below the map disappear when the upper or side menus are clicked on. Cliking the map moves the map to the front but not the b...

Its most obvious on the far right, the hidden cells in coulmn 80 are 25 degrees so even with cell averaging I should not trace as low as 23. Under light loads below 3k rpm it seems like a roll of the dice, sometimes it follows the map and sometimes it pulls timing. No knock cells are on the map and ...

Interesting that the timing map / idle timing were inverted with the offsets Yeah, I don't know if it I had it wrong before adding the third offset or if one effected the other. I had a bad ping and lots of heat with a trailer a few weeks ago and started digging. I loaded a tune with flat everythin...

So is it okay now? yes, all good starts and drives now but with a quirk I also noticed the other day. Before the engine is fully to temp: there is a spot under light load and low rpm where the timing access a map other than Idle and the main timing map. I did some playing around and discovered it w...

The ECUs have some tables relating to AAC duty, which i have found in some ECUs (such as HCR32 RB20) but I don't have the definitions available for this one. I was under the impression all M30 were AT? You are correct, all M30 were AT. This is a swap, MT pathfinder with an M30 ECU, z32 MAF and VG33...

Offset corrected above

Lastly, once I got rolling there was knocking whenever I got on the throttle. Nistune was reporting 55 degrees any time the throttle was open. I loaded known good .bins and nothing changed. Turned the engine off for 10 seconds and restarted and everything seemed normal. Bad write requred a restart?...

Just a quick note on TP sacles, there is a pretty good write up in here about scaling and how to make it most functional. But in a nutshell what I have done is gentle idle to redline pull while running a trace and watching a vac gauge and not let it dip below 13-15 HG. This is your light load zone. ...

UPDATE: Today before starting I zeroed those 3 maps. And then made changes from there. The only one that made a difference was "Idle Timing Offset Warm (temp)" It says: "temp" "-40" "Deg BTDC" "20" Taking the 20 down to zero got rid of my cold advanc...

M30 ECU (for automatic trans) 5speed manual is being used This has been a small thing that has been going on for years even before Nistune was installed. I'm just wondering if might be something in nistune that could change it. Whenever the engine comes down to idle, especially after cruising for a ...

M30 ECU I want to start looking into this issue I've noticed the other day. I only get one chance per day (right before work) to observe but it doesn't seem like I can change the amount of advance added to warm up. I looks like at least 10 degrees is added to my idle timing and I don't know what to ...

Nothing has changed since 2018 with the above change If you see a difference, try adding to the address file IDLE_TIMING_MAP_OFFSET=5 That will add '5' to filtered view. Let me know if that fixes it, and I can update the address file Thanks Matt, Until this week I literally haven't touched timing s...
