Can you send me the file or post it here? Tom

It's possible your F-con is set for a different communication port speed. If dip switch 6 on the front of your F-con (under the blue dot) is down put it up (off) and try again. Tom

What USB port thing? Are you using USB to serial converter? If you using anything other than COM 1 you have to change the setting in F-con downloader. Tom

It needs to be powered but doesn't really need to be hooked up to the car. If you have a 12V power supply you can use that to power the ECU. I can find out which pins need to be connected if you want. Tom

Is the ECU powered? It has to be powered. The phone plug (RJ12) should have: nothing black yellow red green nothing looking from cable entry side. Tom

It's pins 2,3,5 on the RS232 plug.

Are you sure you got the pins right? Tom

What version is it?

The ECU has to be powered. They are usually installed with the factory ECU so if it's plugged in it's running your car. Tom

Is anyone with the older version (i.e. 2.x) willing to help develop download software? I just need someone to test it for me. Tom

If anyone has any HKS V Pro files but doesn't know what they are, the file extensions identifies ECU version: *.FP5 - version 3.1 *.F55 - version 3 *.FCP - version 2

No one interested ??? This ECU is 10 times better than SAFC

The 2 (H8/534 & N1 NSR) big chips are not EPROMs and you don't program them. Only the EPROM (chip with white sticker) needs to be reprogrammed, just like in the R32 ECUs. Anyone able to reprogram the old R32 ECUs should be able to reprogram this one. Tom

Item: Nissan Skyline R33 GTST ECU RB25DET Description: This ECU has been modified to use a ROM chip to store engine maps, making it reprogrammable. The stock R33 ECU can not be reprogrammed. The daughterboards used to modify these ECUs are no longer in production and super rare. It’s a direct swap for a stock ECU. I have personally used it on my own R33 Skyline but have no longer use for it as I’ve sold the car. Items Included: 1x Modified Nissan Skyline R33 GTST ECU with daughterboard for RB25DET engine. 1x EPROM with stock maps and removed speed cut. As the item is 2nd hand I cannot offer a warranty, I have however used it on my own Skyline. Postage Conditions: I am able to post this item at the buyer's expense. Asking price: $350 + postage This ECU has also been advertised on e-Bay: http://cgi.ebay.com.au/ws/eBayISAPI.dll?Vi...DME:L:LCA:AU:11

What's the reason for installing the air temp sensor? Can't the stock be reused? Just curious, not having a go. Tom

gold version with blue sticker is 3.1 Tom

It will not work with version 2.1, it uses different commands. Tom

Is your F-con version 3.1? Is it gold with a blue dot like this one?

Here is how to download the calibration file: 1. You will need to build a very simple cable as per attached pic. No level converter or electronic components required 2. Plug cable to grey socket on your F-con V Pro and other end to serial port on your PC 3. Use attached software to download the calibration file An orange light will come up on your F-con while downloading the file. Enjoy, share it with the world and post your files here. Tom

There is a way to download the file if the ECU is not locked. I'm trying to identify some of the maps so a few files to compare would help a lot. Tom

No one uses F-con V Pro on this forum? Tom

Anyone willing to share their F-con V Pro calibration files? It’s a great ECU but not much is known about them. I’m specially interested in the newer gold version. Here is an R34 GTR F-con V Pro ver.3.1 calibration file. Tom

Same question is it the V pro (gold) version? thanks, Tom

Is it still for sale? If yes, is it F-con V Pro (gold)? thanks, Tom

Sorry for the late reply but would you still have the ECV for sale? Tom
