    I can do that.

    The IC7 is mounted in a Mako dash insert.

    That looks great. I'm assuming the LED lamps on the right are for the 4x4 and Rear Diff Lock indicators? What are the LED lamps on the left tied to?

    Correct. Good guess on the diff lock indicator. Mako did not have one for that so I improvised. :D On the left, one is a low fuel indicator and the other is a cruise control indicator which does not function ATM and was also an improv.

    You probably know that answer better than me since I got most of the info from you

    I've been eyeing the Nexus 3 and IC7 for a while.

    Just let me know when to bring it over for install, might need some head work too.

    Implemented this custom feature today, triggered by brake switch. I think I mentioned wanting to try it a few months ago. Noticeable improvement on slowing down at speeds, as your brakes are fighting the engine less. I might try more aggressive retard after a while depending on long term testing...

    Also changed the Idle RPM targets based on In-Gear state to stop the truck from trying to jump into intersections when cold (RPM targets noted from my Golf between the two states):

    Does anyone track their Home and Trigger misses? I'm still getting some hesitation around 2-3krpm at around -5inHg (light acceleration from stop). Wondering if the 3 Trigger misses I logged is what that was...

    I haven't had any other the the occasional single miss during cranking. My error count is only ever 0 or 1

    I figured it out - the brake sensor is being triggered randomly while driving. Probably because it was pre-wired to SPI2 and didn't follow the instructions of having a pull down resistor.


    New topic, do you happen to have a stock dyno sheet saved? I'm curious about the torque curve

    I know @Bandido does but they're in a rather useless and crowded layout, but I'm willing to bet he also has the normal dyno sheets too. If not I think there are some floating in the old supercharger threads.

    Anyone been to a dyno to try and determine their MBTs?

    It's probably getting close to time to put my wideband knock sensors in and start dialing in efficiency through timing and would be nice to compare where those land me.

    @ShiftyShank had a Dyno day but I don't know if they tuned at all

    Looking like April for me since I'm waiting to get the other two local Haltech tacos to go as well.
