Has anyone managed to get around the throttle closing when doing aftermarket superchargers? I've tried the Optimum TQ tables and the TQ based limits and still shutting the throttle on WOT
Appreciate any suggestions

Can you post a log? Are you sure it's not traction control? I've done quite a few 1GR's now (4.5L cammed S/C, custom turbo setups, etc) and I've never run into a throttle closure situation.
Good to know, Im pretty sure it doesnt have traction control as it normally goes off as soon as you start to do a run on the dyno. Will check again today and pull fuse just in case.

I think your 'upsetting' the ABS computer. You can validate this by:
Under Engine/Airflow/Electronic Throttle/Limits/Torque Based/High Load
Set the right half from say 154.9 of requested torque and up, across all RPM's to 84.0 and I suspect you'll find you that'll fix it.

Its a 2009 Hilux 1GR-FE with a TRD supercharger bolted on aftermarket. So working with the NA cal as a factory TRD isnt available
Double checked, there?s no VSC, ABS unplugged is the same
Interesting.. Is this with the native Hilux ECU or a retrofitted USDM Tacoma ECU?
Native Hilux ECU
Care to share the stock Hilux read? Sounds like you've done your due diligence however.
On the USDM Tacoma, the steps I outlined a few posts above will disable the traction control's ability to close the throttle, however stability control still has ability to shut down the fun. I'm curious what differences there are between the Hilux/Tacoma (coding wise). I'm not sure if a support ticket to HPTuners would be of any help to see if we can get some potentially missing tables/parameters defined for Traction/Stability control "tuning".
You need to increase your desired torque. I've only had a few that have closed thottle while being boosted.

i did one yesterday ,the 1gr in the cruiser and Hilux do throttle closing, I shift the limiter to 6200rpm with software and then put the soft limiter on the unichip ,also the injector clamping on the Trd and Magnusson charger ,here the cruisers don't have traction control ,just the Hilux
most of the time is in 1st gear and its not torque based its an internal ETC Limiter map i found it with other software that limits the opening in some situations
Can't you just max out tc/tq tables like on LS ?
