Sluggish In Rain

[GOLDIE]

traction control also torque tags and for your own sake and to save money get the car tuned for extra boost or you will be rebiulding the motor very soon.

TC program would be for the NA engine - I know my TC fails to do the job if I get right up it. Will light up the rears all the way from boost in first well into second if I let it. Unless Simon turned it off completely in the tune but I don't think so. My point is the TC wouldn't be able to handle the power increase I think?

Is the airbox hook up or Is the turbo drawing air from engine bay, just a bit confused when you say it's got airbox but no pod or air intake on turbo?

If turbo has no intake attached then you are drawing hot engine bay air, this has a effect on your Air/fuel ratio which is already stretched beyond your tune, the more boost the more fuel is required, if you hook up a wideband o2 gauge you will find your afr is going to be very lean, it is also worsened by the cold dense wet conditions.

Best thing is get it tuned before you break it, another thing is is it a Turbo engine or a NA with turbo setup bolted on?

If so don't think you should be putting to much boost in it with its compression.

Removing the heat shields won't make any difference except risk of heat damage to engine bay or yourself.

Turbos actually perform better when hot, it's the air intake that needs to be cool.

Correcty you are Steve. Mine does the same. its great on wet roads with Damp brakes..............

I personally think TC or as Goldie said Torque tags which may well coming into effect

Tc shouldn't affect it as it should be making more than what original tune was set for, if anything it won't even be noticeable.

The tc as a sensitivity setting of 1-10 so it will all depend on that.

Now if vehicle was a XT with 4sp auto etc it's torque limits would be set according to the drive line durability unless the tuner changed them.

The Torque settings maybe more the issue but its not going to make it anymore sluggish then what it was with the lower boost setting, The OP said it was fine on lower boost, its not going to cut fuel completely because it is making a bit more power but more so slow fuel and pull timing to limit it at setting

I feel considering the car has not be tuned for a turbo that has been fitted, it's fuel supply requirement will not be met and as I said previosly the cool air makes it worse as the more o2 the more fuel required.

The OP said it didn't have a problem before upping the boost, with the lower boost not requiring as much fuel as the now set higher boost.

Even still the fuel delivery would have been very lean as the tune was for na.

More Air = more fuel or you get lean.

The LSFT (low speed fuel trim) being the problem as it's the sudden increase of boost that

requires more fuel then what his ecu is set to deliver.

As it switches to HSFT it isn't effected as much yet it will have lean afr.

Also we don't even know what map sensor or boost sensor is fitted and weather they are plugged into the ecu, not to mention the ecu won't even be set for it.

The OP needs to give more detail to be able to get the right help as well he is going to need a tuner that knows what he is doing to sort it properly or it will blow.

I'm no expert tuner but that's what I have learnt and maybe some time soon a expert tuner will reply to this.

ok guys

the car is a previous ford ba XT with a bolted turbo setup. I was reading post that between 5-6 psi the afrs are fine but between 7-8 is when they start leaning. MY CAR is running RICH. I can smell the fuel!.

nothing major but goes away after awhile comes back when driving slow. <-- that a tune would fix im guessing.

the car currently runs a stock xr6 setup

the turbo has NO INTAKE, but the standard cross over allows one for the air intake box on the opposite side of the battery, one for the cooler pipe, and one ive blocked.

there is no intake on the turbo I am purchasing a knn filter but once again turbo is sucking in hot air this current moment.

im thinking somehow the turbo is pulling in water from somewhere as some1 previously stated.

its not traction control.

the car runs perfect in normal weather.. its just the rain that it starts slugging like crap.

im hoping to get it tuned soon based on the the car running really rich atm cause I can smell fuel and hopefully can save up for an air intake and re locate the battery..

its alot of work so far its taken me 3-4 months to put the setup on getting the oil pressure right and working the perks, I pretty much contructed my own piping n all. so hopefully some of your guys ideas can help me with this problem as you guys have in the past and I can finally call it a day with it.

=)

im hoping!

Why is it running rich, did the tuner set it very rich on the na tune?

What injectors are you running?

Are you running map and boost sensors?

What Ecu?

If you are getting water in I think you will find it would start fouling the plugs and cause a splutter

not a dead spot.

Now if you are getting splutter it could be spark plug gapping needing closing up a bit.

even if it is running rich at idle does not mean its got enough fuel when boost comes on.

if you are not running correct sensors it is also going to have problems.

Also the ecu wont be set for boost compensation so it wont add fuel when boost comes on.

Before you go to a tuner make sure you have all sensors installed and find out if the xt ecu can accomadate

boost settings.

if not look for a Turbo model ecu.

Are you using a XT ECU?

Another thing could be the cam advance may be to slow for how quick it wants to rev now.

That may cause a a dead spot.

You are saying it comes and goes, could be signs of the vct sticking, a problem I have heard before.

drop boost back and test it, if it goes back to normal, then the vct should be right so you can eliminate

it being the cause.

most likely the tuner set it as rich because it was his FIRST attempt at tuning crow cam stage 2 cams. the car wouldnt start at all when I installed the cams. I wnot be taking it to him again though.

I didnt think boost sensors were required in the xt, usually you just need a map sensor and fuel regulator for it to be tuned. but this would be when you take it for tuning. I havent installed the map sensor, I will in the next weeks I also have BILLS haha.

what do u mean in regards to a splutter?. I have put the boost back down to 0.4 bar and its holding all the way unlike 0.5 bar which woldnt hold boost. im new to the boost world.

right now its working perfectly fine. come rain it will be again sluggish... I can upload a recording of it if u guys want if me gong first/2nd/3rd? I just fitted my in car cam! =)

im hoping its water oging thru and that I DONT need to install boost sensors n crap cause that's going to be a real bitch as I have little patience with hard to reach wiring ! hence why im delaying the map sensor.

what are your thoughts?

the cam timing is also an idea as it was tuned for an N/A who knows its impact now due to the rise in boost/power.

might have to take it for a tune real soon.

p.s do you think I should put a pod on the turbo so incase it can stop perhaps water going in somehow?

any ideas I might be just buying some wires to relocate battery, weld up a tray or use existing if I can take it off and make a brand new air intake for the turbo but that a whole new project sigh*!
