    Gen90 DIY mapping/calibration thread

    Not sure, but in the interest's of the thread and everyone else, feel free to share your calibration. I don't believe we have any cals for boosted stuff in our 'library' yet. :-D Out of interest how did you find it in comparison to the standard ECU with the PIggyback Module for the ED low...

    Gen90 DIY mapping/calibration thread

    I did try. Spent a little while on a couple of occasions with him helping using Teamviewer. We got to the point he was emailed guys who knew at GEMS, and then gave me the info about the on-broad controller for the previous version sensor. He was great, and I put some money in his kitty for his...

    Gen90 DIY mapping/calibration thread

    Myself and a number of other people have tried contacting GEMS themselves either privately or via the forum, and just get directed back to KTEC Unfortunately. https://www.gems.co.uk/gemsforum/viewtopic.php?t=719 Yes, that's correct, an aspect is an exportable part of a cal file you that...

    Gen90 DIY mapping/calibration thread

    OK so yes it has an onboard wideband controller, but that only works with an LSU 4.2, which from what I have read is the previous generation Wide-Band Sensor, as opposed to the LSU 4.9 that the was included the wideband external controller kit I had that I actually purchased before this ECU. The...

    Gen90 DIY mapping/calibration thread

    You'd really think that wouldn't you. That's also what I thought. Until I started trying to make it actually work. It shouldn't be quick and easy... It is the basis on any ECU. I totally agree. The CJ110 Chip is the inbuilt Wideband Controller, as I was crapping on about few posts back. To use...

    Gen90 DIY mapping/calibration thread

    I agree that's how it should be, however unless I've missed something, all the pinout information on here (I've collected every single bit of info I can find on CS and anywhere else on the Internet) give you all the details of the pins used (by default), and none of the pin numbers for any...

    Gen90 DIY mapping/calibration thread

    One thing to note is there is an unknown number (Well I don;t know the number) of Gen90 ECU's out there that DO NOT have the CJ110 Chip used for the LSU 4.2 controller, as for an amount of time during the global chop shortage it was not included by GEMS to the spot on the PCB marked U25. I have...

    Gen90 DIY mapping/calibration thread

    If anyone HAS had any luck with either GEMs or KTEC getting anything but dribs and drabs of info, I'd love to know. Andy from Phoenix has by far been the most useful so far, as I believe he used to work at KTEC when the ECU and their ITB kit was originally being developed, and was able to at...

    Gen90 DIY mapping/calibration thread

    I'm in the same boat, and couldn't work out which spare input would accept a full 0-5v Signal from an LC-2 External Wideband controller with an LSU 4.9, and even with the pinouts and other information on here, which list used analog inputs, but not spare ones, or what voltage capabilities any of...

    Gen90 DIY mapping/calibration thread

    Actually - I know it's a long shot, but I don't suppose anyone has access to the data from similar tables off an OEM ECU, EIther with a Stock or a RSTUner type tune? I figure Renault probably know what they are doing in the way of idle control, injector angle etc, voltage and temperature...

    Gen90 DIY mapping/calibration thread

    OK, Well this is a DIY mapping and calibration thread, So let's talk about all the other ECU tables and settings other than the obvious fuel and spark maps. I'm trying to teach myself this stuff, and there a few bits and pieces in the base map I got that I think might be 'suboptimal'. First...

    Gen90 DIY mapping/calibration thread

    BTW, ANyone looking for Gen 90 GIN files... It's not particularly intuitive, but if you are using GenTuner Pro, it actually puts the GIM files in here when you install it, however it doesn't set this to be the default folder to search when looking for GIN files. By default c:\programdata is a...

    Gen90 DIY mapping/calibration thread

    Looking at doing the same thing, however, From what I can see the above pinout is for an LSU 4.9, wheras the pinout for an LSU 4.2 is different: So by my reckoning, the table for connecting an LSU 4.2 to a gen 90 should look like this: Bosch Pin No. Gen90 pin Description 6 21...
