Hi Everyone,

Just wondering if anyone else is having the same problem as I am...

When cornering hard (only on right hand turns) if my fuel tank is 1/4 full or below the engine cuts out until I get around the corner a bit. I'm guessing its due to the fuel pump not picking up the fuel because of cornering how I, on the odd occasion, do. I have low king springs and KYB shocks on a 2000 TJ Magna Sports, so I'm guessing I never really noticed it before the springs because I couldn't corner that hard.

I am pretty sure its fuel starvation cause I believe the Ralliart Magna's had baffling put in their fuel tanks to prevent the same problem arising...

Anyways, I was just curious as to how many other people may be having the same problem.

Cheers,

Cruicky.

change your fuel filter, this will help quite a lot :D

How??

It's got nothing to do with the fuel filter mate, my TL does the same thing, i am figting to get something done about this. Form what i gather it's the pickup pump in the tank. Mine does exactly the same thing.

I am gona spit it with mitsubishi, they told me not to drive os hard and i told the service manager to go and **** himself. I was promplty escorted of the premises.

i am interested as this happens in my tr magna. will say a bosh fuel pump help? or how could i tell what the problem is. my symptoms are the same as cruicky_82 at 1/4 or below it is as if the brakes are pushed hard whilst flat to the floor on the accelerator and after straightening up it lurches into action spinning the wheels in second

It's got nothing to do with the fuel filter mate

Well i was gonna say this but i thought i'd give the boy a chance to explain himself.

if the filter is realy blocked it can cause a problem, the pump sits in a swirl pot and fuel return line returns to the pot if the filter is blocked slowing the fuel flow there aint going to be much fuel in the swirl pot,

always check basic things firstl

I'm pretty sure another fuel pump wont make any difference. It would just be the fact that the pickup isn't in the right spot. Or the fuel tank wasn't designed for the driving we do...

I have the same problem in a TF :doubt:

Just gotta remember it and take it easy around the right handers...

if the filter is realy blocked it can cause a problem

True but it would cause a problem all the time and not just when cornering etc. It would also happen whether the tank was 1/4 or completely full.

This guy is saying this is happening only when cornering and when the tank is below 1/4. I'd say this rules out the filter fairly well.

not always ...you would find there is even less fuel in the swirl pot maby on a rh turn, the pickup might be on the right of the pot and when turning right the fuel goes left starving the pump

like i said check the filter first

take the filter off and try keep some fuel in it,

hold fingers over both ends of the filter and give it a few good hits on a hard surface..

turn filter up so the fuel runs out the IN end of the filter pour it in to a glass jar
9 times out of 10 it will be black if its done 20000km

when you drane most of the fuel out try to blow into the in end it should not be hard to blow through the filter (dont sniff or drink fuel. taist will be in your mouth for the rest of the day)

if your realy keen use a hack saw and cut it open

it is a common problem for all 3rd gen magna until the TJ series 2 when they changed the fuel pickup location

i have a TH and it happens from 1/3 tank

only soultion I KNOW of is a surge tank or fuel up before you get low

I used to get the problem quite a lot. so i went to a mechanic and asked what could be causing it, and he said from his experiance with magna's, a blocked fuel filter is the most likely problem as it cant keep the fuel going through at a high enough pressure.

so i think, hmm.... doesnt make much sense, oh well, change it anyway and see how it goes

no more problems... i can fly around corners at traffic lights etc at 60km/h and i dont have the prob anymore, even with it sitting below the E with the fuel light on

that was proof enough to me

A surge tank will fix the problem. The easiest way is to make sure you've always got your tank 1/2 full and/or dont drive hard when it's 1/4 full I guess.

Things like filters and all that should be changed regularly anyway, it doesn't sound like there's a problem...fuel surge happens with all cars with low amounts of fuel in the tank...hence the need for surge tanks.

haha the other week my car actually died around a right hander. but thats cause i went around an uphill roundabout twice.... kinda fast.... and i was like "OH ****!!! what have i done!! :cry" haha, but then when i got back onto the flat the car sprung to life.... :P

There's actually two answers to this one and it's not blocked fuel filters. Firstly, Megatron and KB are on the money with the low amount of fuel and that's what it is most of the time on right hand turns.

Mitsubishi also have a system called TRACE Control. It pretty much kicks in when you're doing something you shouldn't be and basically cuts engine power.

Also, use the search feature. This has been identified heaps of times.

like i said check the filter first seen the problem before filter fixed it

I'd have to disagree with the operation of the TRACE control Redav. Mitsubishi's trace control is directlly tied in with the traction control (and is only fitted to 5spd auto boxes as far as I'm aware) and it does cut power, but not as an anti-abuse feature, but it is there to try and keep the car tracking in the chosen line. :P

My understanding is that fuel starvation during cornering is a problem recognised by MMAL on the 3rd gen Magna, and in 2002 as part of the Ralliart Magna program they developed a special baffled fuel tank for the Ralliart.

To that end I haven't experienced fuel starvation in my vehicle, so maybe the baffles work (that said I never had this problem on my previous TH - maybe I just don't corner hard enough!!)

When I spoke to a service manager he said it's in all 3rd gens. Maybe it's not used in all cars however seeing as though others on here like this guy, here's what Julian Edgar says:

And Gladys comes to life even on high speed country corners, flashing the TCL light and dropping power when there seems no need at all for the intervention. Despite being billed by Mitsubishi as a world-first in its design and operation, the TCL system is pretty dumb - it has inputs only from the steering wheel angle, throttle position and wheel speed. One of the problems is the so-called Trace Control function of the TCL. This looks at the inputs and decides if you're trying to corner too fast. If the internal map suggests that you are, a fuel cut and the electronic throttle kill power. But there isn't a lateral or longitudinal G-sensor to tell the computer what the car is really doing, perhaps explaining the split personality. Fitting grippier tyres, hot or cold days affecting engine power, the presence of wet or dry roads - Gladys doesn't want to know anything about these.
So according to him it's a TCL function. Whilst I wouldn't call it an anti-abuse system, he says it kicks in like I said. It won't make it follow the chosen line, it will just reduce something like over / understeer. I'm not saying it's effective, he obviously thinks it's dodgy but people could be experiencing it.

Like I said, it is there to help keep the car tracking the chosen line (didn't you read any Magna brochures lol ). Once the "internal maps" as Julian put it decide the car is understeering it will reduce power to try and tighten the intended course.

How effectively it does this, I don’t know. I can guarantee, none of my TFs where ever fitted with this, or the TH my dad used to have.

I'm pretty sure trace control was first added to the traction control system of the 5spd autos in the TJ series.:P

The TCL trace control first came in on the TH Sports fitted with the then 4-speed tiptronic auto. I remember because I bought my TH Sports new back in 1999, and Mitsu in those days was making a big play about it (marketed as a kind of an early stability control). It's basically linked, as stated before, to the traction control, but works by cutting engine power when the computer thinks that you're getting "over enthusiastic" in a corner.

I found it bl**dy annoying, and always used to turn it off when in the dry. In just about any corner, you'd find it cutting in and dramatically reducing power. It was recalibrated to be less invasive on the TJs and beyond, and fitted to the five speed autos across the wider Magna range. Anyway, I was glad to see the back of it when I got the TJ manual.

The fuel starvation problem is separate, and obviously anyone in a TE-TF, or in a TH or TJ, TL that isn't fitted with traction control won't be affected by the TCL issues.

These would be 3D software graphs that plots the wheel angle, throttle position and wheel speed and if one of the readings go above what mitsu have stated then it would drop the power.

Just out of interest does anyone know if the evos use g sensors or if they use wheel speed sensors to sense where to send the torque?

There you go, available from the THs. As I said I was pretty sure (not 100%) lol

How will it try to tighten the intended course aside from cutting fuel? Adjusting the steering? :nuts:

All I said it would do is decide you are doing something you shouldn't be doing and then cut power and that's what he's said.

Apparently those auto owners needed someone to hold their hand :bowrofl:

how do u change teh fuel filter??

My TL VRX does this, as did my TH Sports. Bigger spill pots are needed I think, I remember that's what the Magna Production Race cars had to combat this.

the TRACE control? that on 5 speed manual TH sports' ??

cause at the time i was maybe..... driving abit hard... or very hard... :roll:

No it just cuts fuel to reduce understeer. Nothing more nothing less ( I never said it was an advanced dynamic control system). This is how Mitsubishi marketed it and explained it in the brochures :D

The in line fuel filter can be found if you follow the chasis rail forward from the passenger side rear wheel. It's an smallish aliminum looking canister, probably about 40mm wide and 80-90mm in length.

I'd presume it's just a matter of undoing the hose claps at each end, and replacing - but would probably be advisable to "depressurise" the fuel system before hand. I'll check the service manual out, and let you know on Friday night.

I'm gonna replace mine very shortly, because I've experienced this in my new car 4 or 5 times now, and I was under the same understanding as you - that the fuel pickup had been modified from TJII series onwards.......

It closes the throttle(hence why there are different throttle bodies for traction control), and this will cause bviously less fuel to be used. Its a crude system but this is not what was being asked. Its a fuel starvation problem. Many of the people complaining of this have manuals(no TCL). My old TE used to suffer from this too. Ralliarts and AWD's do not suffer from this howver.

Agreed, I was just discussing the trace feature of the Traction control system with Redav.
