Hondata

Sorry to posting so many times in a row but I just figured something out. I read online that sometimes the data cable comes unplugged from the flash pro and to try opening it to check the connections. Well I opened it and tried connecting the data cable without being attached to the flash pro and it...

Also when I have the key to the I'm position and plug in my flash pro the chiming stops and my coolant temp gauge turns grey and if my car is started the VSA light and Traction control light stay on and I even get a check engine light for the display losing connection. Without the flash pro connecte...

Damn there wasn't a fuse in slot 23 and I put one in but I'm still having the same issue. All of the connectors look fine too. I can hook my OBDII scanner and it gets power fine. Are there any other possibilities? I'm trying to avoid sending in my ECU for testing and be without a car for a while.

I forgot to include that I am using flashpro manager 3.1.5.0 on a 2009 Civic SI.The connectivity problem has existed with all previous versions of flash pro as well. Another odd thing is that even though flashpro manager does not show that it is connecting to my ecu, my flashpro history shows that i...

I have been having connectivity issues with my Flashpro. When I try to connect it to my car the power light comes on for a few seconds then turns back off. When I try to do it while connected to my laptop everything but the ECU is checked and still will not connect. I read online that it could be my...

Alright I sent them an email, I really appreciate all the help.

Unfortunately that did not work either. Do you have any other suggestions for me?

Sorry to keep replying multiple times. SInce you guys will be closed by the time I reply, what's should I do if those works? Should I flash it back to stock while it's connected, or what does this test tell me?

Alright it'll be a couple hours till I can do it but I'll give it a shot. Should I unplug just the upstream or both?

Nevermind I just reread it and saw you said "sensors" lol

Update: I uploaded the new software but it still will not connect. Once again it just greys out the ECT gauge and does not detect the ecu

I also sent an email on the 3rd but it's not a big deal, I got an answer so I'm happy. I don't mean to be rude I has just getting frustrated. The serial number is FP-SI-US-230874 for the 06-11 civic si. The version of flash pro manager I'm using is 3.0.1.0. I just got a notification that a new softw...

I have an 09 Honda civic si. it started after I loaded the injen CAi calibration. I got it to connect long enough to load a MAP based tune that ran better but I can still hardly ever get it to connect. The laptop recognizes it but it wont pick up the ECU. The pins on the flash pro module are all str...

In case anyone has the same problem, I didn't have race tunes checked and was only choosing MAF based tunes. The intake is too big for the MAF to compensate so you have to run it on a MAP based tune. After I did that the A/F ratios were much better.

I guess I'll make a thread here because Hondata won't reply to me. I bought a flash pro and everything was fine for the first day. I uploaded a new tune and it was working great. The next day I was going to datalog but my flash pro now refuses to connect. The power light turns on for a couple second...

I recently installed my Skunk2 Intake along with a Hondata basemap. No matter what intake calibration I use it ends up running lean. It's a 3.5 inch diameter cold air intake and if anyone could help me out it would be greatly appreciated.
