Ac is on 99% of the time.

Hmm, not good news then. I wonder what triggers the fan to come on to cool the condenser then as I know the coolant temp sensor is obviously duff. (Shorting out the sensor causes the fan to kick in)

I've been suspicious that my AC system is low on gas based on the noises it makes. It also produces little to no condensation from the drain after a long drive. I'd assumed that it was down to the fact that it was cold and not having to work much.

it might not be the sensor as the fan is on about 10 seconds after a cold start with ac although it will disengage if the ac's pressure drops to far and as you say the dash shows normal temp.

when the ac is on on yours is the clutch actually engaged on the compressor?

I don't think so, now that you mention it. I don't believe I've heard the compressor clutch kick in. Clutch could be knackered I 'spose.

I reckon I need to change the coolant temp sensor just to be on the safe side. I'll need to see the garage about getting the AC checked to make sure it is holding pressure. I'm suspicious that they didn't do the aircon service in august last year.

if the clutch does not engage (the ac turns off due to low pressure etc) it doesn't trigger the fan other than when the engine is hot

get a re gas along with a sensor

Stuck waiting for the coolant temp sensor to arrive as PFS were out of stock so it's coming from sweden. Spent some time giving the map some work to hopefully adapt it to suit the change in behaviour since removing the heatplate.

Reduced the boost request a tad at the higher rpms as I feel it was slightly high. I've also reduced the pressures for the lower TPS settings which should help make the throttle pedal feel a little bit more linear.
Image

Had to make quite a big change to reg_kon. I've raised it a lot more at the beginning to help boost rise a little faster.
Image

Finally a comparison of tweaked vs the standard ignition timings

Done some more testing today. The ac compressor does kick in briefly after startup but I reckon the pressure is too low for it to work properly hence why the compressor doesn't remain running and the fan doesn't run to cool the condenser. Running the ACC on LO gave an in vent temperature of 13.5 degrees so it's definitely not working.

Further testing also revealed that the coolant temperature sensor is in fact working just fine as the fan did finally kick in today at a precise temperature of 102 degrees. Was out for well over an hour and kept the laptop connected for data logging and the temperature hovered between 82 and 91, averaging at about 85 degrees. I still can't believe the difference in how the thing drives since removing the heatplate. It's lost all of that jerkiness when coming off the throttle and no more "kangarooing" when trying to crawl at idle. It is now butter smooth to drive.

I did some data logging to see how the changes to the map had affected the boost control. Still not quite right but not too far off.
Image

The turbo is a lot less "laggy" than it used to be too, I'm now getting 1 bar of boost around 2.2K where it used to be around 2.6K.
Image

This log is back from when I first started tweaking the boost control to reign in overshoot. The lag is easily observed here.
Image

This is the data log from the dyno run in 2012. Notice that boost doesn't really peak until 3k.

Psst, what did the heatplate do other than mess up the car?

if you live somewhere REALLY cold it helps warm the intake... useless in this country

New sensor arrived. Since my original actually seems to be working just fine, it's going into the spares box for now. (haynes manual giving misleading resistance:temperature info) Also got some caps for the lug bolts as being exposed to the elements is corroding them.

I got some caps and completely forgot i had fitted them. That led to a very sweary hour or so trying to remove a wheel and wondering which of my sockets was the correct size. The flimsy "cap remover" was more flimsy than remover as well when i realised my mistake. :oops: I now have a number of broken caps.

If you know of a reliable tool that can remove them from the depth of an alloy wheel i really would like to know about it.

Never tried these before and it sounds like I'll have some "fun" then.

I'd prefer to go back to wheels that have the hub covers like super aeros or the older vikings, but they aren't as common as I'd like.

I know I have some, somewhere. I will buy a new pair soon. Then I can put the other set of caps on the car.

More new parts.
Image

Windscreen trim (my original has gone very hard so worth changing seeing as it's not drastically expensive)
Dipstick (the yellow bit on mine is well past it's best and will probably break as it feels brittle)
Coolant tank cap
Fuel line to rail bushings x2 (noticed that these were knackered when I stripped the fuel rail off to sort the heatplates)
Stanchion arm bushings (Garage warned me that they were cracked last year)
Spring clips for bushing bolts (These are usually just rust/dust by now)
Bushing anchoring bolts (usually chewed to a knarled mess)
Trim clips (Most of mine have split)

Ooh interesting. Where does the Nikon lens cap fit?


:) :) :D

Fitted the new caps. They look a bit out of place as they are too clean, if that's even possible. I've also noticed another difference since removing the heatplates, which is significantly less noise on boost in 5th. No idea why, assuming it's a turbulence thing. MPG improvement is looking excellent so far, 160 miles into this tank of fuel and DTE is still hovering around 350-400 which if true would net me somewhere around 35 which is a massive improvement on the 28 I've been averaging for a while now.
