T5 rubbish in 1st gear

[tim15888]

Had my car mapped the other day, scince having it done it is obv much faster, boosting higher, easier to drive at low speed in higher gears and also slightly better on fuel. Unfortunately though, I havn't managed to test it propperly off the line scince having it done a week ago as it hasn't been dry. Found a dry patch today, and gave it some off the line. Dissapointingly it was really flat, like it's not boosting in 1st gear, or starving of fuel. I don't actually think that it's related to the re-map to be honest, just wondering if anyone on here has had the same problem and knows what it is? I've had the problem before from various issues, like when I had a knackered MAF in the past, or turning my bleed valve up too high etc, but I've tried another MAF, and I'm not using the bleed valve any more, and those times it was happening in all gears and this time it's only in 1st, and is perfect in other gears. I have a suspician that it might be the fuel pump causing a fuel pressure issue, and my friend who breaks/repairs Volvo's suspects the same. Just wondering if anyone has had the same problem in the past, or has had a fuel pump pressure issue and whether the symptoms are this?

I don't usually ask for help on fixing stuff, but this is a weird fault which doesn't make a whole lot of sense. The car doesn't know it's in first gear so why is it being a shagger in 1st only? Unless....the clutch pedal switch isn't making contact propperly.... Maybe not, just thought of that one as I was typing and was actually talking to myself when I typed it.

I'm all ears if anyone has had the same problem

Mine doesn't run any boost in 1st gear... it's supposed to be that way AFAIK.

If you got full boost in 1st... i suspect it would just be a nightmare anyways

[tim15888]

Yea, doesn't get time to build up to full boost in first, but it was faster in 1st before the re-map.

[Wobbly Dave]

1st gear is usually over so quick there isnt time to build the boost. Even so you need to ensure your actuator is adjusted properly.

[tim15888]

Actuator hasn't been messed with, that's the problem though, 1st gear isn't over very fast. It accerlorates from 60-90 in third faster then 0-30 in 1st...

[Wobbly Dave]

Has it been checked though?

[M-R-P]

Yeah, check your actuator - grab the rod, if it moves easy with one hand, it needs tightening.
Since I fitted my cone filter, I can always hear my turbo spin up and since the last time the ecu was reset, ive been training it to be more aggressive but i never hear the turbo hit top speed in 1st. Something springs to mind about torque limiting in 1st gear with ME7 but that may be auto.

Everything keeps up with me in first.... 2nd... less so

You fuggin knows it monkeyman

When you hit boost in 2nd in a T5.... check your mirror, you'll see the other driver looking down to check if they've left their handbrake on.

[M-R-P]

2nd is awesome nd probably my fave bit about the big sweed, although in this current weather, i can't stamp 3rd lol.

[t5_monkey]

Ha you gotta tease it! Mine's pretty good in the wet usually get a good hookup in 2nd as long as you feed it in a bit.

strut-brace, good dampers and poly-bushing all help with the front traction.

Here's your brown bag to breathe into

Perfectly normal to me. 1st felt really flat after I had mine mapped but it was just that all the other gears pulled better than before so I put it down to a sort of an illusion of relativity <man>...

My old Rover 620Ti pulled hard in first gear but the gearbox wasn't built for it on the long term. Hence the reason most of them didn't go on far past 100k, if you abused that hard first gear. I sort of understand why the T5 doesn't do a good drag in 1st. It would probably eventually tear itself apart if 2nd is anything to go by..! (I always thought 1st in the T5 was more like gunning an old 3ltr Ford Granada off the line!)..

A spot of damp and the thing would just sit their spinning.. I never thought of the T5 as a drag car. I hated having to race people off the line. They need 2nd onwards to really impress. Live with it.. !

Mate, I know how to spell, she's called "The Big Sweed" - white on top, getting darker going down (dodgy plod respray). Wtf, pmsl, lol Pmsl etc

That makes it even funnier

Maybe add a kind of turnip-top to it to set it off?

Thats what the leicestershire plod lightbar was for lol

[wegal]

might sound odd, but is the clutch ok ?

Mines not fast in first mainly cos its an auto, but it does build to full boost if you let it, only downside to that is that the wheels will start to spin and not stop till you hit 5th in the wet lol.

Also is your car an auto ? and did you delete the torque limiter ?

I doubt fuel pressure as I would have thought that you would have the same problem throughout all the gears, it would be determined by engine speed and load and not the gear selection.

[T5frankie]

mine is a bit loony in 1st gear same as all the gears lol
