    Boost leak testing would be fairly straight forward on these cars it seems. However, since there's two turbochargers and thus two inlets, you wont be able to test from the turbo onward. Frankly testing from the turbo inlet isn't the most accurate way anyway, since boost pressure still makes its way past the journal bearings and into the crank case (while the car is not running, of course). So, if we assume the turbo compressor housing gaskets as well as the outlet O-rings are intact and...

    Alright so I've been made a fool by my own ignorance and impatience again... Turns out Garry you was right, the "Coolant Temp" option does in fact read way higher than actual. I ran the "Coolant Temp Scaled" at the same time as the other option and there was a noticeable discrepancy. At ambient temp, both the outside air sensor and temp scaled were reading 18C, whilst the other option was 21. Then I let the car idle for 30ish minutes and the scaled option rose more slowly but gradually, and...

    I don't trust the dash gauges. On my other Mitsi (using the same coolant temp sensor and sender) I have seen the gauge remain in the same place but one case it's 90C the other is 105C, a very significant difference. Also I have been told especially more modern Mitsus use specific 'filters' on the gauges which keep them more in one place and doesn't let them fluctuate too much. In other words, the gauge might read a wee bit below the mid mark, but it still may not be safe, i.e. it might be...

    For the life of me I can't get these coolant temps down. I am using Evoscan 2.7 with the modded Vag-Com cable. I haven't touched any data items or definitions within the software, I just use it for logging. No matter what I did, temps seem to be between the 97-100C region, especially now after changing the lifters, oil and rebuilding the turbos (thus having to drain most of the coolant and adding it back in again), the temps in my logs are 99-100. Fans kick on but on the slowest setting,...

    Tell you hwat buddy, that makes perfect sense. I might as well connect that grey wire to the other one behind the speedo as you say; it would be more helpful to have a speed signal for logging, at least for now. Thanks to everyone for the help and diagrams!

    Yes! My wiring near the ECU connectors looks almost identical, with the same grey tape and thicker white wires which have smaller black ground wires going inside (but I haven't torn it up since I didn't want to dismantle more stuff). It's June 2000 car, so as somebody mentioned, a 'second facelift'. It also seems to have the good ECU since I could easily connect to it through Evoscan and a cheap VAG cable. So what you're saying is, the VSS has a single wire coming out of it which is...

    Right so here's the situation. The grey wire coming out of the converter chip (ECU output) was in fact soldered to random non-factory wire. Then that wire lead all the way down near the ECU connector 4, and was soldered to the VSS speed signal wire directly; the white+green stripe wire and two silver dots. As far as I've read on the forum, that's the wire people cut to eliminate the speed limiter. However, as we have found out, it also cuts signal to Evoscan and any other diagnostic/logging...

    I completely forgot to update this thread after starting my converter chip woes... It's an aftermarket horn installed by the previous owner (now confirmed by him after a call). The pump-like unit is the electric compressor motor which draws in air, then channels it through the transparent hoses which lead to both horns. The car still has it's factory dump valve in the stock location further down, so it's not that for sure. I guess I got mislead by that sheet of paper by Ralliart that had check...

    I appreciate you guys' help. The way I see it; before I messed with it, the ECU was in fact getting a speed signal. Now, after cutting the grey (ECU Output) wire, the ECU doesn't read a speed value anymore. That grey wire simply must be the wire that now carries the corrected speed signal to the ECU from the converter. On some google pics I noticed that these converters come with wires pre-attached to them, including a grey wire. They appear to be no longer than 3 or so inches. So, by that...

    June 2000 is the build date albeit first reg in UK is 2002. It's a facelift Type-S auto Galant estate with AYC and the gray interior pattern. I will be removing the kick panel tomorrow to see exactly where it leads to, I am guessing either spliced into an existing ECU wire or directly to one of the ECU pins. I am 99.9% sure I didn't see its other end cut anywhere on the gauge's harness.

    Well I found out by trial what the grey wire does, but I have yet to determine where it comes from and where it leads to. Went for a hoon earlier to check how the new coolant is and if the new boost gauge works (steady 0.4 bar which is great if I've read right?) and even though my speedo does work in kmh now, after checking the log in Evoscan, I could see that the data was nil. Whilst a few days ago, before messing with the MPH converter, the logs did show speed date albeit in mph. So,...

    The diagram appears mirrored, as the vertical connector is actually on the left side when looking at the cluster. Anyhow, you can definitely see the grey wire in my second pic, I have a red arrow pointing to it. Lighting doesn't do it justice but I 100% guarantee it's grey and not white. In which case, if we follow the diagram, that puts it as Pin 11 on connector B, which says it's not used. Usually when pins or connectors aren't used, they don't even have a wire going into them, so I don't...

    Correct, that wire was cut and the blue/yellow wires were lead to the mph converter. I rejoined them so I got my speedo back, but now I'm left wondering if this gray wire is entirely standalone or if it does in fact lead to the car's original harness somewhere. Maybe they just spliced it onto the ECU plug? Trying to save myself of removing the kick panels and pulling the ECU.

    So I got around to removing the pesky CARTEK mph converter module (car is now in an EU country using KMH again) and I am left with one wire which I'm not sure where it goes to. It's a gray unmarked wire which seems to have a factory sleeve. It lead directly to the mph converter chip behind the gauge cluster, and it was attached to the "ECU output". Does anybody know where that wire is meant to go to? I'm guessing it comes from the ECU, as I can sort of trace its sleeve going down behind the...
