Re: hi! from a newbie in canada. rb25det neo, in 240sx

They are not codes, but warnings if load amounts from ECU go over what is in the logs then I raise it as a potential issue. People kept asking me why they were getting cuts etc, so I try and detect what might be the issue and put it as a status message. Only the DTC window has ECU 'faults'

Re: No start after maf calibration

Not for the throttle body. Sounds like airleak or you have it too lean, or its not enough fuel. Unfortuantely no logs or anything to work from to really give you anything useful to work from. Try taking a log with wideband data included, and then we can work from there Also please read our tuning gu...

Re: hcr32 rb20for25 vct question

Use factory VCT parameters during the test and whole the vehicle at TP > 50 and RPM > 2000rpm whilst driving when doing the log

Re: hcr32 rb20for25 vct question

No I don't know any more than this. Fix was done in Oct 2015 in the VCT patch code, and batch patcher. There were no changes since

Please take a log and post the BIN file

Re: Engine temp drop.

Do you have a fault code? Perhaps measure the resistance of the sensor at the ECU plug

If you disconnect the sensor, what does the temperature show?

Yeah seems like it, if you are concerned about the indicator not showing on the screen. Both in tuner and stream modes?

Okay just read your second post, and sounds like you did similar to what I already suggested. K constant values (stock) are the same, so no issue there. Latency I noticed was different. Not sure why the switch over temp (60degC) was changed to 0 in your EPROM file so left that Attached is 21P01 with...

Z31_VG30ET_1987_21P01_MT.bin used the map copy function to copy over all maps that were changed on my tuned image This will probably not work, since the other ROM image is 1988 26P01 and should have different map locations 2. ECU ID on my Nistune board shows as 23710-21P10 It matches the stock file...

Also make sure in Consult Channels Digital Control register 1,2 and 3 are enabled. If older firmware, reflash the board with what I attached

Re: hcr32 rb20for25 vct question

Latest firmware on the board?
A31_FOR_RB25_11U00_74L0F_TPS_VCT_ACOUT_v5_FP.ent dated 15/10/18?

I just tried it then so I can confirm software (1.3.5) and firmware (attached) are fine

Re: No start after maf calibration

If it starts with only MAF changed, that is strange, since 480CC to 1050CC injectors should result in half the TIM (total injection multiplier). If it isn't starting then try putting TIM back from around 250 (half way) to 512 and see if that works Other trying is start again with stock MAF, and then...
