Thanks for coming back to me. The owner said that the original 4bar sensor was faulty and the unit ended up going back to Link and came back with a 7bar map sensor fitted to which is was mapped with. It sounds a bit dubious, but I can only go on what he's told me.

Hi Adam, When you said the MAP sensor isn't calibrated correctly, can you elaborate please? I've tried to calibrate the sensor, but it threw up and error due to being outside the tolerance of 5kPa. I've since looked into using custom calibration using cal 4, but I'm reluctant as the 7 bar setting should be for Link sensors if I'm not mistaken.

I've had a go at calibrating the MAP sensor and I'm getting the message "MAP Sensor Calibration command failed: Current MAP <5kPa or >5kPa of baro reading. I brought up the MAP and BAP gauges and the MAP seems to be out. BAP = 98.6 kPa MAP = 89 kPa. Any ideas on how to correct this? I've been told by the owner that the ECU was originally sent back due to a faulty MAP sensor and Link had replaced it with a 7 bar sensor. When the calibration was attempted, the hose was disconnected to the MAP sensor and blanked off at the engine side.

Thanks Confused, since I last posted I have been lost in a HPA EFI Fundamentals and Practical Tuning course. I watched through all the courses once and I'm around 30% on my way going back through the courses again, but this time, putting all of the information into my own words in a hardback A4 book. It feels like I'm back at school, but it's honestly the way best way to go about getting the information to stick for me.

Thanks for the feedback gents, I have relayed the information to my buddy and have tried to get the car booked in at the tuning garage that look after my car as they can be trusted. In the meantime, can anyone recommend a resource of information for me to learn more about mapping? I'd really like to learn the ins and outs as it's something that interests me as I have a fair amount of knowledge about engines in general, just not the mapping side of things.

Apologies for the late reply, I've been busy with work and left this for the weekend to come back to. I couldn't workout how to change the display units, but I followed your instructions regarding the additional parameters for logging. I've attached a new log as well as the map. The car was running very lean which was making me very uneasy so we stopped, took a break and then came back to it. AFR's were hitting 20 on idle so I ended up adding fuel on the mixture map to get us back. By adding more fuel, the car came on boost, but was still being held back. I feel it's definitely a lack of fuel issue. The only thing that hasn't been changed in the fuel system is the FPR. Fuel pressure was lower this time (248 kPa) around so it's worth taking a look at that. Thanks for the help, I'd love to see this car running as it should as the owner is a bit low at the moment and I know it would lift his spirits. VINNY 15OCT.llg Vinny MAP.pclr

Ah, right. I'm glad I posted here as I did wonder if I was missing something. Thanks for clearing that one up. I guess it's back to the drawing board which is annoying as I had hoped I found the problem.

Howdy chaps, I'm wondering if anyone out there can shed some light on an issue a friend is having with their Mitsubishi Evo 6. The car has a misfire when coming on boost which felt like ignition cut so I did a log and noticed the MAP reading was very different to what the mechanical gauge was reading on our run. While we were out, the car wouldn't exceed 0.4psi on the mechanical gauge, but on the log it looked to be hitting 22psi. Fault MAP sensor? If that's the case, I take it the ECU has to be sent back to Link?

Well, that saves even more wires running off my cigarette lighter lol (j/k). Thanks for confirming, that's a really handy feature.

Does anyone know if the black and red wires that comes from the link CAN plug is a 12v supply or does it need a feed? I'm guessing it's a supply so you can feed whatever you're plugging in via CANBUS.

That's great. I did wonder about the mating female, as well. Thanks for the assist, Adam. I'll get them ordered.

Does 211-4000 mean anything? Edit: G4XTS2JZX

Oh, my bad. I didn't realise there were different models. Does this help?

Perfect, thanks. When you say you can avoid using the analogue outputs, I presume that's using the AEMnet. Just to confirm, I'll need the CANJST plug for this?
