Hi guys, I am wondering if I wire a G4+ into a vehicle to do datalogging only if you can record the fuel duration and spark timing. Right now I am trying to datalog a stock ECU to see how it commands the engine to run to be able to build some of that into a tune.

would be in for a 12 injector ecu.

that wont work until I can use DI11-16 for turbo RPM then

Current setup is closed loop with engine RPM vs TPS. Its interpolating between two maps from an AEM position sensor. I have not yet tuned the boost control beyond wastegate pressure so im pretty open to suggestions but would like to keep the AEM position sensor for different boost levels. Ideally, it would be a user configurable trim table similar to the engine ECT trim where I can trim back boost control based on the frequency of the sensor.

is there a way to configure it as a different configurable input on the di11-16 for the time being to get some reasonable output from the sensor? You can choose "frequency" right now... that would at least allow me to multiply it out on my own. Wiring it to a different digital input would only record up to 20k rpm turbo speed... not useful at all.

I have a pedal unit from a 2008 Subaru STI I would sell... I bought a few pedals to see which one would work the best for my application and have it left over.

+1 on this.

I'm looking at the thunder base map with only 3 virtual aux for the time being I'm wondering if the turbo rpm is available yet on di11-16? im setup to run the speed sensor to 3,750hz with the 12 blade compressor to 150k rpm.

I have a somewhat small turbo for my engine and I have put a turbo speed sensor on it. Its a 2.5L 1jz with an efr 7163 and the efr turbo sensor feeding into the thunder ecu. Is there a way to limit the boost table for turbo speed to prevent overspinning the turbo? I already have the boost control interpolating between two tables for my boost position switch.

You should be able to unplug the idle valve and open the throttle body to get your idle in the rough area of your required idle target. With a cable throttle you would make that just below your target and let the air bleed bring idle up.

Hi everyone... yet another question. Im building my base map now for a 1jz VVTi off of a few different base maps and maps from others.... what I haven't found yet is an idea of how to get the fuel table setup with VE based numbers. Im not looking to be spoon fed a full basemap unless that exists but is there any general idea for idle/low load regions to get started with VE numbers? Details: 1jz vvti Link G4+ thunder internally stock 1jz 3bar bosch temp/map aftermarket intake manifold with 80mm vdo DBW Stock injectors (limiting changes as much as I can to get running, not ideal) EFR7163 turbo upgrade on low boost because of injectors.

Mint, thanks guys.

just following up: I bought the 3bar version of the bosch TMap and I have a question about the calibration... I bought it from Ballenger Motorsports and they have the data sheet: https://www.bmotorsports.com/shop/product_info.php/products_id/1721 Can I use the MoTeC Calibration? http://www.motec.com/filedownload.php/?docid=5134 Does this temperature or pressure fit into any of the LINK defined calibrations? Im not entirely sure how to read the sensor data on the Ballenger website.

I think I will have a spare input to run it this way.... but agree it would be cleaner to do it with a virtual aux. is that something that is in the works for a new release?

Thanks Brad, those two may be a good option should the Cressida Stalk be impossible to find. I would like to try the Cressida stuff to keep it a bolt-in affair.

Would I be able to do the same thing with a second AEM switch for traction control? I am looking at the PCLink software and it seems like I can only make 50% maximum slip. I.e., if I ran my axis types as non driven wheel speed and the other as the AEM TRACTION switch position can I have the first position act as as Traction off and the position being #2-11 acting as both the arming and the slip aim.

I am wiring up a rotary position switch to an AN Volt input and Im wondering how I would configure the AN Volt channel as well as the boost control system to interpolate between my boost tables based on the control tables. Details for the system: -External Wastegate plumbed as described in the LINK help file with a 3port solenoid to the top port of the wastegate. -Using the AEM 12position switch. which has a 0-5v output with a 5V input and ground. ( http://aemelectronics.com/files/instructions/30-2056 Universal 12 Position Trim Pot.pdf ) I would like to have the position 0 as wastegate pressure table and position 6 as my full high-boost table with a linear interpolation between. Any help would be appreciated. thanks, Matt

Thanks Brad and Simon. I will look into those switch units and see how I can incorporate that into my AE86 steering wheel. Understood on the brake switch. I will also be using a clutch switch. My wheel Cressida by HellaFab Fabrication, on Flickr looking at this photo again, it dawned on me that there was probably an OE cruise control button in this car before I bought it. will search for that first.

Hi all, Im looking at some of the Plug and Play pin functions vs the calibration to determine how to wire and configure cruise control on my car. In particular I am looking at the 350zLink and how I could apply that type of system to my Toyota with Link Thunder. The 350z button controls wont work well in my Cressida with the AE86 steering wheel and Im wondering alternatives to the Z parts for a 1 wire hookup to the ECU that could be cleanly implemented with an aftermarket steering wheel. Beyond that, the configuration for the 350z switches show the voltages for each of the switch positions. in the 350z is the voltage from a reference or a pullup in the ecu?

what would a configuration for one of these valves look like?

Hi LINK. Is there a way to connect a Link G4+ (specifically thunder in this case) wirelessly to my computer both to log and to tune? Thanks, Matt

Sounds like a ground loop issue if its not consistent.

solid advice. I was considering putting it in the bottom of the manifold for aesthetics but I didn't consider condensation/fluids.

I am planning to use one of the Bosch 3.5Bar Map sensors that also reads the IAT (link below) on my Toyota 1jz. Right now I am building a large plenum intake manifold and Im wondering what the optimal placement for this sensor would be. Just after the throttle body, mid plenum, inline with one of the runners, etc. Here is a photo of the lower intake manifold and a shot showing the throttle body location and a scrap piece of pipe to give a general idea of my plenum shape. https://www.bmotorsports.com/shop/product_info.php/cPath/129_143/products_id/1772?osCsid=fmlhii32s64a5c6d7b07jh4e93

Hi guys, I may be missing it in the help file. Is there a keystroke or shortcut with the compare feature to apply the active cell(s) of the compared map to the base map tune that is open? This was a feature I really liked with a different ECU system I used.
