RB25DET with R32 ecu VCT Not working

Postby stinger » Sat May 20, 2017 6:40 am

Hi,

How to know which ENT file is program on my type2 board?
I used the "Air Conditioning ouput" solution as described on the "Nistune Feature pack hardware Install.pdf", but if I understand, if my board is program with VFCOUNT.ENT, my VCT can work. Should I use the "Fuel pump idle control output" solution?

(Sorry for my english...)

That is my bad hand writing. I write exactly what is on the board. You do not have VCT support on that board

This is what is on your board:
HCR32_RB20DET_11U0F_MT_MEC-212B_FP.ent

You will need to remove and have it reprogrammed (using base image programmer) to this:
HCR32_FOR_RB25_11U0F_MT_TPS_VCT_ACOUT_v5_FP.ent

Thanks for your answer.
When I received the Base Image Programmer, I could play with!! :)

Hi,

I think get a problem with VTC.
I updated my board with "HCR32_FOR_RB25_11U0F_MT_TPS_VCT_ACOUT_v5_FP.ent " and map with "HCR32_FOR_RB25_11U0F_MT_TPS_VCT_FP_maps.bin",
Using Air Conditioning ouput".
Pin9 from ecu is cut and pin9 to pin113 are solder.

If i understand pin 113 operate like a ground. When no ground, VTC off.

At start and for few minutes, "VTC sol" lights in red.
I have 12V at VTC Connector. Ground at pin113.

After few minutes, "VTC sol" become grey.
I have again 12V at VTC Connector. Ground again at pin113.

I have all time 12V circulating to VTC Connector and pin 113 all time at ground, even when I modify VTC parameter for cut it (minimum speed, Temperature cut...).


When VCT is connect, idle is little bad.

You are measuring VTC incorrectly with your meter. You must measure 12V with red probe on meter and pin 113 (VTC) should be on your black (ground) probe

You may need to adjust VTC TP enable higher so it does not affect
