Nistune Formal Release 1.2.21 [update]

[Matt]

Version 1.2.9 update
Further testing found I broke the VQ map K constant calculation with the MAF resize! This has been fixed now

[Matt]

Version 1.2.11
Reset consult register list (to enable TP selected by default on ER34/WC34)
TP min/max filtered representation updates for S13 CA18DET and ER34/WC34
Add copy as BIN functionality to RAM trace panel (copy to hex editor)
Add boost sensor limit/recovery tables (replacing TP limit) in ER34/WC34
Change boost sensor input to volts
Add boost sensor min, max, hysterysis parameters for ER34/WC34
Crash fix: Heap crash on GUID for serial port name scan
Add extra boost tables and parameters for S14,S15
Add boost solenoid duty cycle gauge for S14,S15

Version 1.2.10
Translation default path bug fix

Going through S14/S15 and ER34/WC34 boost control code at the moment boost solenoid and boost sensor values added. Will also do a Volt > PSI for the ER34/WC34 in the next built.

Found that ER34/WC34 boost sensor is used to pull fuel out on throttle stabs. When there are changes to the vehicle configuration or K constant is moved too far it can cause a hesitation on acceleration. Looking through this code at the moment to reduce the effect and replace K constant with Total injection multiplier for this vehicle

HCR32 RB20DET (plus RB25 VCT)
BNR32 RB26DETT
HCR32 RB20DET
P11 SR20DE
S14 SR20DET

Is there any way to allow changes in boost when flex fuel is being used too?

[Matt]

There is only boost output for S14-S15 models and that is not controlled by flex at the moment

[Jono]

okay thanks.

Was just looking at the boost duty on the R32 RB26, maps are there, thought it might be possible.

[Matt]

Forgot about that ECU. Yes it should be possible to add it to a future firmware release for all three. Just need to trim the total duty cycle by an extra flex referenced table

[Jono]

awesome stuff. That means that even the boost will be automatic when the good fuel goes in.

I'll try and get those maps working soon. Not even sure what sort of boost the factory solenoid can even handle.

[Matt]

Have a look at the other threads. About 14psi on the S14. You can either drill out the restrictors or replace the solenoid with a MAC valve

[Matt]

Version 1.2.15
Sanity check window size and locations
Add G20 SR20DE and ER34/WC34 RB25DET feature pack support

sweet

Version 1.2.17

Add MAF function transfer tool
Updates to S14, S15 SR20DET ENT files with 16x16 flex fuel updates
Add TP index back into gauge view page

Version 1.2.16 Internal release

HCR32, BNR32, Z32, S14, S14A, S15 updates removing knock maps, adding flex fuel map
Split out 1995 AT/MT ECU part numbers for A32 maxima
Fix Z31 ECU ID listings
Fix RHS O2 voltage range
Add Flex Fuel adjust offset gauge to firmware and Nistune software

Following recent testing, I've decided to remove the knock maps from the ECU and use these instead as flex offset maps (16x16 cells). So far only S14-S15 are tested and released as ENT files. I'm updating the others but need to test these next week when I get more time (putting my phone number on the website is proving to be problematic as I'm getting a lot more queries now)

The most important update here is the MAF translation tool. This will allow you to use the HPX (original), HPX2, GTR and 350Z sensors in larger custom tube sizes and redecrease the load range so K is not affected so much. I've put together a MAF technical notes document covering everything you need to know so about this tool and MAFs in general. Its a draft so just putting it here for now
