TPS calibration in the Link is extremely easy, I'd adjust the throttle stop before doing something dodgey like drilling a hole in the blade.
Close the idle valve and get the warm idle at the right rpm by adjusting the throttle stop, then you should have enough range of operation with your idle valve to deal with cold start and electrical load idle up/AC
Once that is done you turn engine off, switch the ignition on, do a TPS calibration and save the map

remove the additional wires from the CAN connector that goes to the ECU, so you only have the two CAN wires.

Link A Loom

the single 5V splits out in the loom to run to multiple sensors

I'm currently using an IAT1-8 in my Subaru, have it mounted in the intercooler pipe just before the throttle body. I'm changing it to a T1 Race fast response sensor which will be mounted in one of the TGV delete ports, it's 1/16npt https://www.t1racedevelopment.com/product/t1-fast-at/

Ground offset. check what voltage the ECU is reading on the analogue input compared to what the LM-1 should have on the output
-
Yes, I used to get the same thing before I changed the power management settings. Check the power management settings of your USB controllers
-
is that when the screen has gone off or does the tablet go to sleep? There's quite a few power management settings in Windows that could cause it to stop logging while the screen is off

I'm working through a new map for a turbo 1zz I've been tinkering with for many years. When I next get to the dyno I'll be trying a 4D fueling setup, with MPG for the main table, TPS for the 4D table, and TPS for the VVT table. Will be tuning the main fuel table with the VVT and 4D tables zero'd out, when the main table is done I'll then do the VVT and 4D tables after that.
If that doesn't work out nicely I'll give it a go with TPS as the load axis for the main fuel table with a BAP/MAP XOver equation load source.
Have had the turbo setup running for years with the VVT load set to TPS and Fuel table as MAP, but looking to make it a bit cleaner

using a single tuned map you can easily have it range between 300-600hp, simply by leveraging Link's boost control. You don't need to be switching fuel and ignition maps for different power levels. What ECU does your tuner recommend?

I'd avoid using the auto tune function if you're not using a dyno to progressively work through the map. On the street it will just make a mess of your map and it looks like you're already getting some very large steps in the fuel map around idle. Mixture map with decent filtering is a better solution for street tuning
-
looks like you'll need to do some configuration of the knock control setup, you've got cylinders reading way over your knock target at idle.
To add another row/column to any of the tuning tables, select the table and press X, then hit the green plus icon for the axis you want to add to and type in the value you want.
-
I'd get it running and let it warm up, then adjust the master so the fueling is roughly right, then you can start the fuel map tuning. The 1zz turbo I'm currently working on has Deatschwerks 60lb injectors on the stock returnless fuel system and it needed a master of around 8ms for the idle cell values to be around 30 for a petrol AFR of 14.4 in traditional fuel mode
-
you didn't have the either CAN channel setup to receive lambda from the AEM. I followed the instructions in the Link help file for the AEM gauge and set it up on CAN2 to receive User Stream 2, as your config already has some stuff setup to transmit on CAN1. Don't use closed loop fueling while you're trying to dial in the fuel map, you'll just end up chasing your tail. Only enable closed loop once the fuel map is fully tuned.

a Thunder would be my choice, no need for external controllers or extra complications: https://www.linkecu.com/products/wirein-ecus/g4-thunder/

does the map sensor calibration succeed? the vacuum reading at idle seems off. The turbo 1zz I've got here idles with a MAP of 25kpa , yours is idling around 85kpa. If it was my car I'd rewire your harness to have the ECT and IAT sensors connect to the analog temp inputs instead of the AN Volt inputs. Then you can use the built-in Bosch NTC calibration and 1K pullup resistor
-
damn, was looking at a dash solution for one of them so I'll use an Arduino with the can stream to get this working which may turn out to be a better long term solution

went to test this on one of my cars that runs a G4+ Storm Black today and noticed there's no datastream option in the Configuration Window of PCLink, checked on another car I work on which also uses a G4+ Storm Black and it was also missing there. When I checked on my daily driver that uses a G4+ Plugin it does have the option. Is there a limitation on the G4+ Storm, or some other way I can get it to work?
-
Awesome, thanks Adam! I'll have a look through the list to see if it's possible to display the lambda coming in via CAN
-
Have you tried the "Mx5 VVTi" trigger mode with both triggers set to rising?
-
that's really disappointing, the main reason I was wanting to use it was to display lambda
-
had the same issue with AFR not displaying, I'm waiting for a new tablet to arrive before I look into it more
Idle setting for open loop and closed lopp

If the idle is oscillating, I'd look to adjust your base ignition and fuel tables to stabilise it first
