Re: s13 ca18det FP1 launch control switch input

It's been a long time since I've done the code for this, but there was a MAF calibration input, which was hard set at the MAF. So we were able to reuse this line without affecting the MAF otherwise

Re: s13 ca18det FP1 launch control switch input

We didn't want to accidently activate/deactivate for each gear change with neutral switch (for example if no speed input working, or if not wanted). So other switch was added (it was difficult to get working too) FP1 is push on/push off. I updated that in FP1.1 to temporary push on, as that worked b...

Re: Which is the right PMAS HPX Maf to go with the nistune tables?

We only support the N1 unit as you can see in the drop file for the MAF list

Re: Injector resizing reset ?

I've got my crank tables set as pictured for 1000CC (HPX MAF with mine)

1150uS for the latency

Not sure about your UEGO. Bad placement or sensor not working properly. Add more to the 'total injection multiplier' to add more fuel over the whole range

Re: vg30e

This is what the ECU does when it is reaching about mid rpm/load it will switch from sequential to batch mode with the two banks of injectors. Effectively firing them twice as often, so reducing the injection time by 50% to compensate If this causes an issue when going on boost, you can tweak the ba...

Re: Injector resizing reset ?

You need to sync (either download or upload to the board) before making changes

Re: VH45de Type 3 ecu issue

Yes you understood correctly with the fix for the RPM limit As you noticed, the current version address file also had the DTC flags. This only stops check engine light and DTC codes appearing in Nistune Mapping guide on our website has the details for each map. The Alpha/N table simply tells the ECU...

Re: VH45de Type 3 ecu issue

I've fixed in this file, so upload this first with the current address file (WORD) addressing if you uploaded/burnt this in the ECU

Then move to the fixed address file with BYTE addressing after and adjust RPMs

Re: VH45de Type 3 ecu issue

Might had used the wrong version address file when I posted the updates for the offset on here The numbers should show as single bytes, not words like you had REV1_LIMIT,&HFFB4,1,1,1,50,Rev. Limit 1 REV2_LIMIT,&HFEF5,1,1,1,50,Rev. Limit 2 REV3_LIMIT,&HFE75,1,1,1,50,Rev Limit CEL See atta...

Re: VH45de Type 3 ecu issue

Log is looking better Would put min load (TP) a bit higher to prevent such a lean out on decel. This will increase minimum TP allowed For acceleration you can see stock AlphaN (where throttle enrich makes TP go to max load). You can reduce this to prevent over fuel on full acceleration I'll have to ...

Re: VH45de Type 3 ecu issue

With fueling, I'm not sure yet from the log since the TP was an issue. Might need another log, but the early ramping in your fuel map is an indicator of an issue. Probably you had this due to early spool up of the super charger. We are seeing 45% duty in the logs

Re: VH45de Type 3 ecu issue

With the TP. That is strange, it is not added properly to the consult table You will need to manually add it in, then burn to keep it for next time 1.

Re: VH45de Type 3 ecu issue

Some ECUs have an extra 'offset' added to consult output from factory. Unsure why but I had a look at the 1993 address file (yours is 1994) and we have entries: CONSULT_TIMING_OFFSET=45 IDLE_TIMING_MAP_OFFSET=45 Copy the attached ADR file over your current one in the Documents/Nistune/Address folder...

These have been recovered now. During the transfer we used FileZilla for FTP and by default it backed up all the files as TXT mode (instead of BIN mode). All looks okay now
