Rang to see how the car was going today & the bloody P0106 MAP CEL code has reared it's ugly head again & the idle & revs are real erratic. This is the same problem I experienced last winter & earlier this year leading to Mitsubishi replacing the MAP sensor in an attempt to fix it. CNJ are trying to solve it & if they can't it will have to go back to Mitsubishi before they can finish the tune.

On a good note they have managed to trim the injectors back to give me a flat 11.8 AFR right through the range & the supercharger with no water/methanol injection is only puting out 3.5-4 PSI boost (no fuel or water to seal the rotors). Still got some sorting before the water/methanol is introduced & have only seen about 175-180 KW at the wheels (stock TMR380 output) since they are having problems tuning with the MAP code making the throttle body operate with a mind of its own.
well there are some positives to take out of that at least!

Im suprised its only making 4psi, should be more than that even without the water spray, mine still makes 11psi without any extra from my water spray (not tuned in yet) and drops to 9psi at max revs

:hmm: Maybe they put the wrong pulley on it???? Oh well will have to wait & see what happens once the other bugs are sorted.

FOOZ, what does AFR mean mate.

Make sure there aren't any vaccuum leaks
Happened to me and wouldn't boost up past about 3psi

Ok thanks, will call again tomorrow & check progress & let him know to check for leaks if he isn't already onto it. Actually maybe that could have something to do with the MAP (Manifold Absolute Pressure) sensor probem too???:hmm:

that said if it was a boost leak, that would also be a vaccum leak and with a MAF sensor not reading the extra air being sucked in post sensor, the car would idle bad.

I think we might have found the problem foozr. low boost and bad idle definatly could be caused by a vac leak. My car on the standard cams ran at 20 inches of vaccum at idle, and seeing your 380 runs the same cams as i had, it could be some useful info for them so they know where to aim at.

Sounds like you guys might be right, will call CNJ in the morning & let them know so they have something to look for. I'm just wondering if it might be the phonolic spacer not sealing properly as I think the MAF problem I had last year would've started after that went on.

Any updates today?

Any updates today?

I rang early this morn & gave him our theory. Said he had already had a bit of a look for a boost leak & couldn't find anything. Said he would have another go today & introduce some water spray. I didn't hear back so I assume he is getting somewhere. I told him I didn't need the car in a hurry so just fix it.

Fooz, what's the go?

Fooz, what's the go?

Dunno, I been too busy to call CNJ & they haven't rang me. Will call tomorrow & check progress, I'm heading overseas early next week so might not get to drive it before I get back :doh:

Looking for this one to come through with the goods, all the right gear is in place to do it

Well here's hoping, like I said earlier, hopefully no news is good news. Can't see why I can't get the power I'm after, might just be some teething problems. Oh well it's like just about everything I have done to this car, someone has to be the pioneer for the masses lol

Fooz, what's the go?

Well I rang CNJ today & because I said no rush, he has been working on it between other jobs. So far he has been concentrating on fixing the MAP CEL problem of random fluctuating revs & he has pretty well sorted that but there is still a MAP P0106 CEL code. He hasn't put the water/methanol into it yet & has a very conservative tune in it so far & the low boost level, so still under 200kw.

I told him I was heading off overseas next Wednesday morning so he said he will keep it & work on it next week while I'm away, so hopefully when I get back I might see some decent figures.

Once I get it back I will have to take it to Mitsubishi to track the problem with the CEL. They have checked all the settings & the MAP sensor is operating correctly (already replaced by Mitsubishi) so looks like it must be some other sensor or ECU playing up. The unfortunate part is they may wipe my warranty on this, but since it was an existing problem before the supercharger went on they might cover it ...... hopefully.

So what does the P0106 CEL indicate?

It's making progress so that's good.

You mean, you still have a warranty?:nuts: LOL

Manifold Absolute Pressure is not what the ECU thinks it should be for the current operating condition. The sensor seems to read ok, I have monitored it with my OBD2 scanner & CNJ say it looks good too. From what I can gather the ECU takes readings from other sensors to arrive at a value it wants to see from the MAP so obviously something else is giving an incorrect indication.

Ummmmm warranty, why wouldn't I have warranty? They won't notice the blower surely? :doubt:
Seriously the service guy at Zupps Aspley knows me reasonably well & knows of the previous problem. In the end it is up to them if they solve it & put it through as warranty. I can only hope :pray:

Fooz

When you back from O/S or whatever?

:iough: I'm back, guess you're after an update?

Not much to tell so far, as you may have read there were a few initial probs before I went overseas & when I got back I rang & they were stumped again by my water/methanol kit programming. The software wouldn't save into the controller, but I just had a call & they reloaded the software after downloading off the manufacturers website & it is now working. Last thing he said was, it must be a big jet coz there is water coming out of the exhaust pipes. :eek2:

They are now going to get some methanol, tune the water injection & crank some timing into it, along with doing the failsafe second map. The boost without water was 3.5PSI which doesn't seem right so unless it comes right up with the water I might be chasing another pulley to get some decent boost. :headbange

Did some posts go missing I wonder

Anyhow, what is the latest on the Supercharger test and confirmation of being good by Sprintex

Haven't heard yet, meant to send an email this morn before I took off but forgot. Will send one off tonight so should have some info tomorrow hopefully.
