    hey guys, having a little issue after installing link. car is acting funny when getting into boost, drives perfect until it kinda hesitates while around 2k but once it hits about 2.5k it clears up and drives fine which has never happened until i installed link. ive tried adjusting a few things like Timing/Fuel/MAF and havent really gotten much as far as results. can anyone let me know whats up

    thanks

    What size injectors? If we don't use the same WB as you, we can't see what's going on with your afr's. So logging wbFactor will help with this.

    You have a launch limit of 2500. You might have a messed up clutch switch that's activating at that rpm. I forget how that whole system works but try unplugging or plugging it back in depending on how it's currently setup.

    Good eye!! I just saw that too AND his clutch switch isn't working. Put the launch limit to 4500 and see what happens

    Sorry didn’t realize I forgot to put that info in, stock injectors 450s, and I was told the AEM wideband that I have is no good with link so I haven’t hooked it up with link. My AFRs stay in the normal pump gas 14.7 range while cruising just for reference

    You can see that at 21 seconds the inj duty cycle goes haywire. I'm assuming it's cutting fuel for some reason. Maybe there is a brake switch on the autos that I don't know about?

    Funny enough on my way to work this morning I felt it cut fuel for half a second right around those same rpm

    My guess is there is a brake switch on the auto that is disconnected and once you installed link, there is that launch rpm that gets activated that isn't available on a stock ecu.

    There is a way around it but you won’t know until it’s wired in. I’d wire it in and just splice the new wb if/when you get it.

    Well after raising the launch limit, it didn’t seem to do anything, it still seems as if the car is struggling around the 2k rpm mark but clears up at 2.5k

    You do not have CAS inverted in ECM link. Is this a 95 ecu in a 97+ car? looks like car is running EVO timing map?

    Yes I was looking at that setting and wondering if I should pop it on LOL and that is the evo timing map, I had tried the 1g,2G, and the evo map, and the evo one seemed to drive the best so I just took out timing where my car was reading knock, but as I said I am new to link so could be just me being a noob
