Timing issues

Re: Timing issues
I may not be able to fix the Consult reporting when in/out of gear. This is something Nissan consult reports to us. I provide the ability to report the consult values, but it appears they are not correct when at idle (ie 5 deg BDTC out) since you have confirmed the table values are now correct
Idle timing maps are referenced when in gear/neutral
Injector size - I used the same values as Z32. If you can confirm the M30 is 180CC (this seems very low, I would expect 200CC at a minimum same as RB30E) then I can update it

Re: Timing issues
Ok, I think I can live with a minor reporting discrepancy since I know that it is really doing what the map says and not what Consult reports.
If I can find my test results from my injector cleaning a few years ago I will share it. In the mean time I did find this:
The M30 was an NA Single Overhead Cam VG30E like the NA Z31, 85–94 Maxima and 90-95 & 96-00 Pathfinder(Presently I am running the 96-00 Pathfinder Injectors). The Turbo motors came with 260cc But the NA motors came with 180cc.Matt wrote:I may not be able to fix the Consult reporting when in/out of gear. This is something Nissan consult reports to us.

Re: Timing issues
Thanks. I've updated it. Only used for the resize option
Re: Timing issues
I found this on an older thread. I'm going to add it to the file and see If I can get any closer to my actual Idle numbers. I will report back with all my offsets so they can be included with future updates.

The other settings work fine;
CONSULT_TIMING_OFFSET=45
TIMING_MAP_OFFSET=5

EDIT: Nope, 0, 5, 10, -5, no effect on reported Idle timing.IDLE_TIMING_MAP_OFFSET=

Re: Timing issues
Did you view Idle timing map in 'filtered' rather than 'raw' mode?
Re: Timing issues
This is in reference to Reported timing in the consult window view vs actual timing.
But I guess you're right, that modifier line would affect the map view and not the consult view.
It says [RAW] on the top of the Idle map window(I don't see a drop down for filtered views) and the reported timing Still becomes correct when I get into the regular timing map.
EDIT: found it by right clicking. I'm gonna try some things I'll get back to you.

Re: Timing issues
I know this an old thread but want to confirm the 180cc injectors.
It's also possible that the "temp enrich" has to do with a fuel temp sensor mounted in the fpr and that over a certain fuel temp, it enriches to combat vapor lock and is mostly used during a start after a hot soak.
300zx single cam vg30e had the same thing.
I may be mistaken about thier term "temp enrich" usage but i do know nissan did use a fuel temp sensor......just not sure if this is where it's used.

Re: Timing issues
Thanks for confirming the injectors
There is the possibility some of the temperature tables use the fuel temp as input (rather than coolant temp) but would need to check the code to verify the indexing

Re: Timing issues
Just an update
CLOSED_LOOP_TABLE_TPS_MAX is actually the ADD_FUEL table location (used to access last column in fuel map on full throttle, M30 ECU code slightly different from other models)
Updated for next release

Re: Timing issues
I adjusted my timing gears yesterday and had to reset the ignition timing. Reported timing via nistune in both idle and in the main map match my timing light.
But my Idle/Decel and Idle/Decel Neutral maps are 5 degrees high in filtered view. (says 15, nistune reports 10)
I honestly haven't touched timing in years. The similar issues were resolved in this thread and I left it alone until now. What's changed? The address files? Nistune updates? Is there a new line I should insert like last time?

Re: Timing issues
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

Re: Timing issues
Thanks Matt, Until this week I literally haven't touched timing since 2016 ish I am going to re-check (and make sure everything is in filtered view) and get back you you.
Re: Timing issues
That did it. Here are my current offsets from M30_VG30_256_E.adr
CONSULT_TIMING_OFFSET=45
TIMING_MAP_OFFSET=0
IDLE_TIMING_MAP_OFFSET=5
Consult timing matches light at idle TPS closed and running TPS open.
Timing Map, Idle/Decel & Idle/Decel Neutral match consult.
Thankyou
Re: Timing issues
Offset corrected above
Re: Timing issues
Awesome, I'll update the address file in the installer
