PC to ECU Interface

I just bought Blazt consult interface. But I can't get it to work!!!

My laptop doesn't have a COM port so I'm using a USB to Serial bridge they sell along with the cable.

http://www.hand.co.nz/300/interface/

I'm using DataScan 1.4.

I've checked the continuity of the consult port to the ecu they are all working.

I've set the software to the port i'm using.

I plug it in to the car, start the engine and click on CONNECT on the software. Nothing happens.

But.... if i connect and then turn on the engine, the progress bar at teh bottom gos up a knotch or two. IF I wait, nothing happens further. I turn it off and then on, it goes up a bit more. I did it till it gets full and then it restarts again. Tried teh free conzult as well. Didn't work. Need help here. Please!!!

i guess this is pretty basic, but are u using the right port? they typically are com3/com4 for usb serial thingys.

so when u click connect u dont even get ecu serial number? can u perform any active tests (easiest one is shutting off a cylinder)

hey i presume that the interface will only work with an rs232 com port. I dont know if using a usb to serial adaptor will work .. also all usb to serial adaptors wernt all created equaly, you may just need a different brand one .. Is that datascan a new version ? i think i have 1.3

mick u should have received new version of datascan in email (im hoping u didnt rip it off someone else...)

usb/serial converters do work (ive got one) - try it with something else though, like serial mouse

give us more info on the car ur trying it on, whether uve tried other cars, whether uve tried other software (scantech nissan is a good freeware one, http://www.geocities.com/obdscantech2000/S...nTechNissan.zip)

datascan is probably best overall. best free ones are scantech nissan, conzult free, and calumsult (http://web.utk.edu/~cjohns32/calumsult/cal...umsult_full.zip)

as for why i asked what car/engine/ecu etc is that consult is not supported on early (89-90) rb20 skylines. consult only came out in 90/91 so the earlier cars dont have it. also no aftermarket ecu has it either.

before u send it back u can always try putting a 10k resistor between TX and gnd wires on the plug (eg on back of plug) however this only tends to help when u have garbage received, not so much when it doesnt connect at all

      Hello, sorry for being late to join the discussion, but my clock just died on me.   Ive tried to look at Michaels digital clock repair.docx and it doesnt work maybe the file has expired.   Please let me know if you can re upload it or take some youtube videos to show us how to get the clock installed? thanks

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
