good work

i cant do anything like that just yet as need rear tyres! replaced front so just the over steering to sort now! fun it is going round a normal easy corner with the arse end stepping out randomly puckers up your butthole a bit!

need a service and cambelt aswell

all 406 1.9 have a bosch pump, but the max fueling screw is coverd by the immobiliser stop solenoid shield, and you have to take the pump off and dril out this cover, also the to adjust the on boost fueling you have to dismantle the pump

ah right, the stop solenoid, are you not able to cut through the shield with an angle grinder to gain access to the max fuel screw? never seen a 406's pump yet.
To adjust the on boost fueling you only have to remove the 4 bolts on top of the 'turrent', mark the valves position, and take out the nylon washer to allow more valve movement, then reassemble.

Now why does this all sound like a recipe for blowing ones engine and/or its components to pieces with over pressure or some such?

Seems to me that if you have to angle grind, cut or drill a casing... then the screw ISN'T meant to be tampered with?!

Don't try altering the pump settings on the 406 XUD as you would on a 306 XUD, as the 406 uses a nasty lash up that controls certain parameters of the fuelling electronically - if you try to alter th max fuelling, and off boost fuelling, the car will try and compensate for this and it'll end up a mess. Derv Doctor can do optimisation on hese motors, and it's worth spending he money to have them get it right first time, rather than spend weeks stopping every 400 yards to nip the screw round another 8th turn!

Ade, you taking the 406 to Pugfest, or d'ya reckon you'll have project Millenium Falcon sorted by then?

at the momment its looking like the '6 but if the missile is done by then i will be warp speeding to pugfest in that

[turbolag]

Aye mate, i'm looking forward to being taken for a spin(!) in th worlds only Merlin powered 205 cabby

[Bonez]

not going in the cabby anymore chap ;)

Thats what i was saying, i havn't seen a 406's pump, i'm only familier with the 306's pump. What does the ecu control on them?


Re: hacking up the solenoid shield. The shield is only to cover the solenoid and stop it being tampered with. If ever you have to replace a failed stop solenoid (either the car will not turn off, or will not turn on) then you'd have to angle grind it anyway, either that or else spend a big amount of money having the pump and timing belt removed to gain access to the solenoid.

Dunno bud. The official line is 'certain fueling parameters', but i've never had a play with one. Mebbe James might know?

i tried everything on my old one, and that shield is one bloody strong bugger, you have to remove the pump and drill out the shear bolts, theres no easy way about it

from another post:

which motors did you say were semi electronic and how does that work?

all 1.9's in the 406 had semi electronic injection and just controls preheating, postheating and the injection angle/timing, injection duration, on boost fueling and total fuel quantity is still controlled by the pump

it works by using a needle lift sensor, throttle position sensor and rpm sensor to determine the angle/timing and a coolant sensor to control the glowplugs

basically it does sod all, and turning up the max fuel screw wont mess up the engine management in anway really, if your worried about it doing anything fit a 306 bosch pump, as they are identical apart from the on boost fuel controller, and the hydraulic advance regulator solenoid in the 406 bosch pump

the only reason they fit the anti-tamper shield and shear bolts to hold it in place is because of the immobiliser as if you could get to the stop solenoid, which the sheild covers, you could easily steal it

the 1.9 td can take huge increase's in power, you just have to watch the coolant temps as they can really hike when pushed hard, my old 306 was running 20psi of boost and LOT of fuel, loads of smoke and it had 166,000 miles on it and ran without a problem, the lads over on pug306.net are running some pretty extreme 306 1.9tds, there's a few that destroy V6's

[philg]

Thanks for the info james. if i buy a 406 xud next she will be getting screwed. i kept my 306 running at standard fueling etc as the engine was the best i'd ever come across, i'd bought it from an old couple that had it since new. A lad i went to school with had his 306 screwed out and the turbo adjusted and had her rolling roaded at 136bhp. That was with the standard turbo, and top mount intercooler too. He's since sold that motor and as far as know she's still on the road, hasn't popped yet!

[turbolag]

He's right - there's a lad in the PSOOC who' just had his 205 1800 XUD dyno'd at 157.4 BHP!

[diesel-dog]

Bit of mixed feeling then when it comes to screwing the old 1.9td. Mine is currently approaching 200,000 miles, could an engine with this milage take anymore, or should I just let old sleeping diesel-dog lie?
