hy my escort rs turbo mfi have a piper cam mongoose exhaust

and brand new stage 2 turbo

and i have a turbosystem chipped ecu

after a rebuild engine and running it in for the luxembourg MOT i put the turbo pressure very low at the wastgate
then i want to have again more boost
i put the wastegate a little bit shorter that was livered the new stage 2 turbo
i tryed the drive the car well the turbo start charging like at 2800 rpm very pushing

but than it s stopped at 4000 rpm and the rpm fall down ..

like a big stop at 4000 rpm with a strange turbo noise likes it stop or hit a wall


to mutch boost? but i have a turbosystem chip in the ecu...

thanks sorry for my bad english

intake pipe closing up

luxembourgrst

sorry but was is that meaning difficult for me in english to translate can you explain more detailed thanks

all my pipes are samco but the hose from turbo to the meetering unit is roose at a little bit to long but fitts ok after somme cutting

luxembourgrst

they say the the stage 2 turbo is up to 20 psi is it mean when they come delevery they are setup to 20psi and that set it up to mutche boost because i touch the wastgate to make it shorter like 3 -4 turn that it was send brand new to me?

like overboost

Turbosystems

all our chips have over boost protection
you will find some numbers on our label I will need these to identify the maps

luxembourgrst

it means that it s my ecu chipp whos stops the ingition.??

Turbosystems

iTrader: (5)

It is possible as it will have a boost limit either at 18 psi or 23 psi depending on the map we supplied at the time
If you supply me the hand written number on the Turbo systems label I will tell you what to set it to

luxembourgrst

ok i will say this

luxembourgrst

ok i just open it there is a sticker on the chip with the number 0782564222 and with a pencil write 79 FD or something and then on the metal over the ship NWT

and there where the vacum hosse come in 14 t

luxembourgrst

99 FD or 99 ED it s not writen in good condition

all the info you need is in the pm's

luxembourgrst

thanks

luxembourgrst

well ok is my ecu 18psi (1.24 bar )limited

i push the turbo pressure down at 1.5 -1.6 bar the car goes better but still cutting at 4500 rpm

then push again the power down like 1.3- 1.4 bar it s runn perfekt but only somtimes cutting in the 3 gear full trottle
after some pushing my AFR still red and still on 22.33 for 3 seconde at then very lean and than continue normal driven again fine is this normal ? not enough fuel

my afr at idle is between 14-15

well i need a no limit ecu chip

smsnw71

I also have turbosystems chip with
88E 188SL
&
99ED AB
Handwritten on it
Is it possible to find spec on this?

luxembourgrst

99 ED is 18 psi

smsnw71

Ok

Get your car to a tuner as soon as possible mate as it requires mechanical tuning, not just a chip.
You are very lucky its so lean as if it was richer you would have holes in your pistons by now!!

As Stu says if you have not had the fuelling set to match the boost you are probably very lean and this is your problem!

mgtkr1

setup is priority when upping boost pressure. could be a boost hose collapsing, boost cut as tony has indicated the chip DOES have a boost cut. sometimes a lean engine will miss fire. I would refrain from driving it hard/on boost until its been setup and checked out. going from 8psi to over a bar is a massive jump, mfi cant fuel for both ends of the spectrum. as mine stands it is on the lean side at 10 psi but fuels perfectly at a bar of boost. and tbh a bar is about the most mfi can fuel for. setting up is a bit of a guessing game and only a experienced tuner should really set these cars up

luxembourgrst

well i just bought a evolution motorsport no limit chip

and i will put more fuel with the meetering unit co srew

how mutch AFR i need for 200 bhp

I predict a missing piston crown thread soon

Don't adjust the CO screw only, adjust the fuel pressure screw. Aim for an AFR of 11ish at higher boost levels. You will be rich below max boost.

luxembourgrst

the fuel pressures screw where is this does we have one on a oiginal srew

its mean a AFR at 11 on hot engine at idle ?

thanks

This, will get messy!

luxembourgrst

no i don t want messy lol and also the engine not

i only want to know wat afr i need on 20 psi boost

or at 18 psi boost

afr on idle and then have to check the afr on boost if its at 11 ?

if not i need more fuel pressure ?

The little black box on the RIGHT hand side of the metering unit (as you look from the front of the car), take it off, turn the 3mm allen key one quater of a turn at a time CLOCKWISE to richen, ANTICLOCKWISE to lean.... You will need a pair of det cans and a WBO2 to set it up properly, adjust the idle mixture screw last.

luxembourgrst

ok yes i know the black box who is fixed with 2 flat screw i take it off and i only turn one quater clockwise and then refix it ? and then put resetting the co srew at idle on 14 ?

thanks sorry for my english

After then checking on boost AFR's and for detonation, yes.

luxembourgrst

hmmm ok well then an other question whats the max bhp power we can have wihtout touching to the fuel pressure?

luxembourgrst

but wihout a WBO2 is it possible only turn a quarter clockwise

Stu @ M Developments

iTrader: (12)

About 110 on some I see that never had the ford fix when new.

Stu @ M Developments

iTrader: (12)

Please take it to a tuner mate. This job is clearly not within your capabilities.
Sorry to be blunt, but it might just save you a lot of time and sorrow.

luxembourgrst

ok yes i understand but where i live there are no tuner only software

well

hmmhow mutch boost can i have without touching the fuel pressure ?

Ben26

well u can tell with your AFR , if its leans out to much at the top then tweek it slighty.

But that is a very crude way of doing it

GO TO A TUNER >>>>>>>> NOW ! lol

Stu @ M Developments

iTrader: (12)

He said he hasn't got a wide and kit mate so he can't monitor AFR.

luxembourgrst

well how all the guys do to have 200 bhp i have piper cam
stage 2 turbo
mongoose

whats the max bhp power without touching the fuel pressure mfi

Ben26

I know efi cars that have touching 200bhp with standard fuel pressure but im not to familiar with MFI.

get a wideband asap mate, innovate ones are spot one then u can see what is going on with the fueling, also put an inline fuel pressure gauage in so if u do tweek it u know what your taking it to



my bad , well he needs to bloody get one asap

luxembourgrst

i have the innovate mtx afr

well how mutch boost with a stage 2 to can allow the mfi to follow

Ben26

50psi

have u got a standard t3 ?
what intercooler do u have ?

stu help this lad out

luxembourgrst

stage 2 t3 airtec intercooler

Ben26

im ruinning 23 psi but with more mods


if that helps
