Display Name posted a topic in G4+I Just bought a brand new G4+ VLLink / HVLC+ for my manual SL VL Turbo RB30ET and id like to hook up these extras i have purchased : XSL loom, six LS2 coils, LC-2 wide band O2 sensor, boost solenoid, air temps sensor & possibly more. I have looked around and i cant find much at all on doing this. If i could get some advise that would be great. Cheers
Hey guys I have a g4 atom on a KA24DET 240sx. Im having an issue with the throttle position sensor setup. I can go into options, TPS setup, correct the values with the pedals and it runs fine. But after next start up, even thought it has been saved and stored, the values start randomly higher. Sometimes even as high as 30% open. Am i saving it wrong or is there an issue with my TPS somehow? Any advice is appreciated, thanks!
Hi guys. I have an unusual problem and am not a tuner by any means but am generally pretty good at understanding instructions. I have a link PNP in my altezza factroy ecy box. Have had it dyno tuned and set up for over a year and ran with no issues. Last week I removed the intake plenum and throttle body to polish the plenum and paint the throttle body. I did not removed the FPS or TPS from the throttle body, merely unplugged them and covered them up before painting. I also cleaned the butterfly valve inside with degreaser. After i reinstalled everything I started car (a week later) and it shot up to 3500 rpm and then dropped to 1500rpm and then continued to bounce between these rpms until i shut it off. A CEL came on so plugged in pclink on laptop and showed error code 75. Had a poke around to make sure everything was plugged in and then started it again,then error code 76 came on as well. Cleared the codes and took it for a short drive and it continued to rev to 3500rpm with no accelator pedal input, almost like it was on autopilot and would drive itself. I performed a tps calibration and calibrated with no problem.Started it up and it went jumpy and had a very fast idle between 1500-2500 rpom and sounded like it was missing lots. Have done some reading on here and seems like it went into a category 2 fault? Went back to it tonight and now shows two more errors, codes 23 and code 26 both to do with the tps. I have checked the voltages at the input wires to the ecu and were as follows : pin O22 TPS sub (red with black stripe) measured 2.54V at 0 throttle and 4.65 at WOT pin O23 TPS Main (Green with yellow stripe) measured 0.782V at 0 throttle and 2.426 at WOT I am stumped as to what it can be, as tps calibrates fine seems to read correctly and I havent adjusted its angle it in any way, merely unplugged it and replugged it in after a week... Any ideas? Also note that for the last year or so the ethrottle motor has made a constant wine noise when key is in the on position.
Davidv posted a topic in G4+Hi, I'm looking to setup E-throttle shortly with an Altezza 3SGE throttle body. On a G4+ Xtreme Red. Question one: Looking through the documentation, it says that it requires TPS main and sub, FPS main and sub wired to 4 seperate inputs. Am I correct in thinking that this is just two wires each coming out of the TPS plug, and two wires coming out of the FPS plug? One which gains voltage one which drops voltage as it sweeps through it's range? Question two: A lot of the documentation now mentions the Black edition Xtreme, and any mention of the Red seems to be gone. Which is fine, but what's the effective difference between the two, am I safe in following the pinouts/guides/etc that mention black version, for the Red? Question three: In the box with the ECU there was a little booklet which had a pinout of the plugs, (I can find this in the online help in PClink) but also on another page a list to write down what you were planning to use all of the inputs/outputs for. I found this useful, is there a copy online somewhere so I can print out another one? Also on a bit of a tangent, but what are peoples experiences with e-throttle? People with Altezzas (with factory ECU) seem to moan that it feels mushy, but I'm guessing it's just because you've got no control over it's logic, and how it decides to use it for traction control etc. Which obviously isnt the case when you're running a Link! What is the response time of an E-throttle if you mash the throttle wide open, is there a noticeable latency at all? I'm mainly wanting it to make the car a little less jerky to drive at low throttle openings... But cruise control will be neat as well
