    2015 Mustang Throttle closing

    Hi, 2015 Mustang, GT350 intake and TB, PMAS cai, 1 7/8 headers, LU47 injectors, first time using HP Tuners on my Mustang. Followed the tuning school book and throttle keeps shutting down and not sure what table to adjust as I am not sure what some tables do.

    thanks2015 mustang r27.hpt2015 mustang r27.hpl

    Disable anti shuffle and correct your torque/inverse. you have a throttle angle error of -11 at 3k rpms

    In the log at 4000 torque source changes from dd to driveshaft, what table would i adjust to stop that or is there more to it?

    Hi, thanks that worked! I was so wrapped up in throttle maps never thought it was a torque limit even thoe it said so.... So I made a run and to me looks like the commanded lamda is not the target and the two sides are very different. Also I assume -5' of knock is pulling 5 out as some have told me they also add timing but looking at the base and take away the rertard it equals the amount showing.

    Hi, it didn't like this one too much, fuel at idle goes -23% to 13% and at wot has the same spread between banks and spark says source is borderline but it doesn't match the map table, closer to the mbt table. thanks2015 mustang with ford racing stage power pack blend-turboanythingmods r 33.hpl2015 mustang with ford racing stage power pack blend-turboanythingmods r 33.hpt

    your sources and limits are correct now . you need a long idle and slow rev log . make sure to reset KAM before you log .your imrc is also forced closed .if imrc is still connected use this

    I adjusted the maf period at idle and it idles fine now, can you see what the target afr is at wot? My o2 shows 13.8 at wot and I lift.

    Thanks

    Do you have harness cable extensions on the oxygen sensors

    .847 is your target . you are only showing .70 max load and then going low . your imrc are closed . you are staying in 1-9 with the imrc set to closed .you should easily achieve 45-48lb of air with the imrc open .you either have bad o2 or a leak in your manifold install forced .85 at wot

    The o2 I was using stopped working so have no idea what the afr is. thanks
    Yes the o2's have extensions and the band clamps 6" after primary are leaking a bit.

    So I am on the dyno today and they dont have anything until late tomorrow, I had a SCT device with a tune but was giving me a lot of drivability issues and the wrench light kept coming on so I bought this HP Tuners device to try and do stuff myself. The shop recommended I do base run with the sct and datalog it, so we did and I can send that to you as well. Afr with the sct device/tune was 12.0 at wot but now the o2 died but was reading 13.8's or so and that's why I would stop the run. The dyno shop here is new and they dont tune cars and are of no assistance to me (import shop) but just for numbers.2015 Mustang base run.csv

    Your file name says imrc on but i dont see a change? Last run I shut off rear o2 as I tried the dyno 02 but they are having issues with theirs as well.
