Still no suggestions? When will the new firmware update be available? I have tried many different settings, but the speedo shows *10 of the actual speed. As long as I saved my map in a newer version of VTS I`m not able to go back to an older firmware either. So I`m kinda stuck to the newest software which has a lot of issues (wideband control, fuel pressure reading, comm problems, speedo problems etc.. )

I belive it has the lastest firmware, but I can try to update it tonight and report back. Edit: From their webpage it seems that the lastest firmware is from 2011, and I`m 100% sure I have this innstalled. MXL Pista & Pro*** 14.86.56 14-Sep-2011 7.3 MB

Thanks, I have set up fuel pressure as an input so thats probably the case then. I`m not sure if its possible to visualise the fuel pressure on the AIM dash when its set as a GP input? When it comes to the speedo, if its reading correctly then I cant understand why it has changed in the first place? Second, its not possible to adjust anything on the AIM dash, I can only choose the input directly from the ecu. Meaning its not possible to do any calibration/modification in the AIM dash when the signal comes directly from the ecu

Another strange issue, my speedo is completly wrong. I use AIM Dashlogger connected to r232 cable. Look like my speed is multiplied by ten (10), the calibration is excactly the same as before. When i`m driving 60kmh my speedo says 600kmh.

I found the problem with the leaning issue, its only present when I have the closed loop lambda control active. Is their any reason why this is only present when using closed loop lambda control on 4.9.3? I have always used the closed loop lambda control, but never had this issue before.

Ok I will try to source a replacement just to try. Is there any way to compare theese plugs up against other so that I can find suitable replacement with resistor? And with regards to your other comment, I always try to compare the MAP`s , but there should be a tool where you could load two different tune files and compare them up against each other. Its really difficult to compare two maps, because there is alot of information conatined on each file. I cant remember all to number in the fuel and ignition table as well as all the other settings in my head. Thanks for the help so far

I got a tips that the spark plugs I use is not protected for electronic interference. I use Bosch f3cs spark plugs. Anyone heard about this? I switched over to theese plugs last year when I mapped for E-85, I have made several connections after that, and also no problems when tuning with the spark plugs when the E-85 map was made.

Ok, I will try some more. I will also call my tuner and ask if theres a possibility to get a new cable. I will also try another computer.

I do have a vipec fuel pressure sender and I use closed loop lambda and AIM dash. But seen on the post further down in the thread its a update covering this pretty soon.

Tried some more yesterday and I belive the Issue could be in my computer. Tried to upload firmware 4.9.3, no problems. Started to adjust the fuel table to compensate for my new injectors, after a few minuts I got an bluescreen. It said: "Too many request" or something like that (also alot of disconnects during tuning) If theres issues with computer, could that lead to a corrupted firmware on the ecu? Every time I upload firmware or maps I get different issues, so maybe its all down to my computer? I run 64bits windows 7, but I have done that since I installed the vipec, never seen any problems before.

yes, of course

A new error, now I cant even get into the map when I`m offline. Tried to remove everything both software and usb drivers and reinstalled several times. When trying to open a map file in the vts software I get the following message: An object has no name(MemLoc=4397, CRover Num=2877) Cant connect to the car and now the idle is even worser than before. I suspect that maybe its something hardware related, I have never had any problems with both VTS and the vipec module before switching to saturated injectors over the Peak and hold injectors I had before. I have of course adjusted the injector setup to reflect the new injectors

Hi After innstalling release 4.9.3 I experienced problems with the fueling. If the car is in idle, about every minute its goes lean (0.1 afr every half second or so) until it goes to 19.4afr and almost stalls out before stabilising at 14.0afr. Everything that has to do with fuel correction (wideband etc) is turned off, no difference when is activated either. Went back to the 4.7.. software.. no issues. I use Vipec v88. What could be wrong? I have just swapped mye lucas 1260cc low impedance with the new bosch 1700cc saturated injectors (have adjusted the fuelmap accordingly and fixed the injector setup) Another question: I have ecu serial number 5091, and to be able to use can bus i need to have a serial number of 10.000 or higher? Is the hardware mod complicated? Is it something that can be fixed locally?
