Hello everyone, so i might be overlooking this but what's suppose to be the normal voltage to ecu for PIN 71 +14V?? My tuner told me that my the g4+ plugin was not seeing a good amount of voltage so he had made a jumper wire from the alternator positive post straight into the (B) Pin 71 thus ECU getting 14V, and had continued tuning my car like that. I eventually had to take that jumper wire off bc it would leave the ecu activated and drain the battery even after I would turn off the car bc it's straight powered from the battery. Right now I only see ~12.8V to the ecu. With car on i have 14V at the battery posts and alternator positive post to chassis ground. Battery is in front of the car, positive cable runs through the whole length of the car into the trunk where the fuse box is located. In picture provided, it's 13V at the 15A EFI fuse White/Red Wire to (Batt) Pin 61: 12.8V Black/Yellow to (+B) Pin 71: 12.8V Here's a log that I've recorded, ECU voltage varies bc of loads like lights, signals, fan, etc.. Can someone give me some advice? Log 2019-12-15 4;37;23 pm.llg
Hi all, I've just started looking into tuning with my G4+. This is my first shot at tuning and the car will almost exclusively be driven on the street. I've been slowly working my way around various functions and getting a feel for what they do and how my car responds. I've been gradually going through some of the HP Academy webinars but still feel like quite a noob! A few details about the car. - 98RON Petrol exclusively. - Walbro 255 fuel pump - CT26/GT35 hybrid (yes I know....) - 540cc Toyota injectors - 3SGE (NA) cams - 1ZZ COPs via an external converter box (Was operating this way on the factory ECU. Will be wired directly eventually) - High flow CAT I'm after any advice on the particular setup, but in particular I'm looking at some help trying to narrow down a low rpm hesitation. It feels like I have very little torque around 1000-2500 rpm. This has pretty much always been the case with the factory ECU and the stupidly oversized/restricted turbo in it, but this I think still comes down to tuning. There are probably a whole heap of things that need to be changed on the attached map. Some may have been tweaked in isolation. Also, does anyone know if the 3SGTE factory knock sensor is able to be setup in the PnP G4+? low_rpm_stutter_3.llg MR2_Modified_Tune_v3.pclr
I have a 4age 20v Blacktop Toyota engine in a mk1 MR2. The engine was installed with a harness from WireGap and plugs into the factory Blacktop ECU just like a factory loom. Runs great. Wife got me a brand new Monsoon for Christmas (I hinted it might be appreciated) and I'm now planning to do coil-on-plugs imminently, and maybe supercharge a couple (3-6) pounds in the future. I'd like to get the ECU up and running sooner though. I need to make a translation pigtail from the "factory" Blacktop harness to the Link Monsoon. Is there a convenient wiring diagram for this someone could share, along with any special notes for configuration (fixed timing advance for first startup, VVT recommendations etc.)?I need a knock sensor. Do I need the Link knock light system, or is the knock sensor itself enough for this? (I'm going to datalog every trip and do nerd science with the data)I need a wideband o2 sensor. I think I need the Link/Bosch CAN lambda sensor (for the extra data), or can the Monsoon read the Bosch LSU4.9 sensor natively?Additionally, any general guidance on a 4age 20v Blacktop would be appreciated. I'm new to tuning, but have been (1) reading forums nonstop for months, (2) watching High Performance Academy instructionals, (3) reading Performance Fuel Injection Systems and (4) working on cars for 15 years. I plan on carefully proceeding to attempt road/track tuning and supplementing my experience with Dyno time for that perfect edge, hopefully after I've achieved a passable tune manually. If I suck at this I'll just go pay the dyno guy to do it for me, but I really want to learn it myself ;-). I need to order a Link A pigtail and a 20v ECU socket to get the harness patched across. This will be a project that unfolds over the coming months. I look forward to learning Link!
