what did you do to your 944 today

ORIGINAL: Frenchy Scam, get some nice new shiny hoseclips the crimp type for those vac hoses, fitted an AEM Digital boost gauge to my car today , only showing 13 psi on WOT so a quick check that i have no kinks in the vac hose which is directly off the manifold and a wee tweak is in order (read turn boost up to 17 psi) nice bit of kit but would have been nicer with a bigger digital readout compared to my innovate AFR gauge which has nice big digits. Sitting on axle stands now with the handbrake getting adjustment tomorrow, whilst in there i will be gunking and pressure washing the gearbox/diff. Stu, you coming to Deutschland in May ?

Yeah will get a nice shiny solution soon for my vac lines. The plan is to get to Germany with you guys. I am juggling a new child though and already got a week's golfing in Spain with the boys booked for March. Mrs Scam will need bringing round to the idea, I am just the man for the job! What is your idle AFR? Mine was in the 16's with a vac hose loose and also caused it to run lean under load. Mine idles at mid 13's with vac hoses attached correctly and high 11's at WOT. Promax L2 chips as you know. I think the display on my AEM is just right, have you been to specsavers?! [8D] Stuart
 
Stu, around 14.3 at idle but can be adjusted via idle mix screw atop the throttle body, around 11.8 AFR on WOT, I just need idiot size digits because i wear glasses and i am too busy looking at the road when sending on so a quick glance over at the gauges is all i can be comfortable with. Will check it out with a passenger, not Jayne as regards some other posts on this forum. Git yerself to Germany lad, Golf .......! Check out what W Churchill said about that [:D]
 
The mixture screw is on the AFM Jim. My AFM is lying on the garage floor, the scivision maf does not have mixture adjustment so stuck with mid to high 13's which is fine. Stuart
 
Gearbox oil successfully replaced in the S2 - I have to ask who's bright idea it was to put the filler and the drain on the side of the gearbox with the exhaust - so after a gentle warm up drive I have to be ultra-careful removing the old plugs (required some serious brute force) so I don't scold myself on the hot exhaust pipe.
 
My 6 year old lad requested a ride in the black turbo,his review was ,"it's fast and quiet, and the roof comes out,this is a good car daddy!"we went to his hockey coaching this morning in it,then gave it an overdue good wash.[:)]
 
Top lad keep him learning ! Stu adjusted my tick over AFR to 14.6/7 via MAF adjustment took the black car out for a run and went and fired the 220 up to let it warm up.
 
Jonny another tick off the list, sorted my boot light t'other week on the 220. the car has one of the fancy Cliifford alarm systems fitted which is wired up to put the interior lights on when you deactivate it.

Via AFM adjustment you mean Jim! AFM = standard barn door affair, MAF = aftermarket solution that lets in more air and improves driveability across the rev range to name but a few improvements!! Don't want to open a can of worms but I would richen that a bit at idle. I run mid 13's on my chips and the boys at Promax reckon that's spot on. Which is just as well as I can't adjust it!! I put my idle speed up to 900rpm yesterday, had been at 800rpm for as long as I can remember. What do others have their idle speed at? Cheers Stuart
 
AFR at idle with the engine fully warmed-up should be 14.7 full stop. If the engine does not idle cleanly there, then something else is wrong. Idle speed should be 840 +- 40 RPM with a standard camshaft.
 
Hi Tom So what's wrong and what's the issue if i'm idling warm at mid 13's? It doesn't seem like a very big difference and the guy who programmed my chipset says its fine and wouldn't want it leaner? Cheers Stuart
 
What happens when you put back standard chips and the 2.5bar FPR? AFR at idle can be 13 only when the engine is under the warm up phase.
 
I don't know, never had my AFR gauge before 3 bar FPR or chipset change. I was running a standard chip the other week for a bit but still had 3 bar FPR, the readings were the same. It could be my SciVision or the maps on the chips causing it. The car seems to go very well and fuels properly under load, mid to high 11's at WOT. Edit to add it idles a bit richer than that at initial start up and warm up phase settling at mid 13's when warmed up. Stuart
 
Thats what i meant Stu adjusted via MAF so AFR was 14.7 which is only in force on tickover, open the throttle and theMAF / Chipset takes over, 14.7 is the ideal stoich mixture so should be clean as a whistle come MOT time plus will be a bit better on the go go juice when just sat it traffic. Jim.
 
I burst both nearside tyres driving over a pot hole. Bollocks! On the plus side, I inflated the never before used space saver and it appeared to be absolutely perfect. I think that Sheffield City Council and I are about to fall out.
 
BOTH tyres Simon? Crumbs, must have been a giant pothole ... Best of luck with the council. Potholes annoy me intensely so I hope you get satisfaction. Oli.

Frenchy's post makes me think that the TPS may not be adjusted correctly? Does it click when it should?

I think so, but will check and confirm tonight. I'm still having the odd vac issue too, every now and then the revs will dip a way down to about 200rpm then catch when clutch is dipped. 99 times out of 100 it's ok and doesn't do this. I am going to take all the vac lines off tonight and inspect them then secure them with little tie wraps. Stuart
