St170 fuel injection on a budget project.
 

St170 fuel injection on a budget project.

I thought I would start a thread on getting an St170 engine to run in a kitcar using its own ecu.

Yes I know you can stick bike carbs on it ect but you wont do it as cheap as this and get the same level of emissions imho.

Budget so far £45 BUT I DONT HAVE THE ENGINE YET

1hr's Work. Can I turn the immobilizer (Pat's) on and off.....Answer YES

A good start but lots and lots of work to do.

I am also on the scroundge :D for any st170 engine sensors that you guys havnt used on the bike carb or megasquirt convertions.

I am looking for

fuel rail pressure switches
Inlet manifold runner controle modual ( even faulty )
Maf
knock sensor

ect

If I get some donations to keep the project cost low I may even do a Full "how to"

:)

Have you actualy disabled the PATS?

TT

That depends on what you mean by disabling it.........

What you see is me turning the immobilizer on and off. Once off or disabled it will not re-activate untill the power (ignition) is turned of.

I am doing this on my dinning table let alone in a car.Just j10 wires to the ecu.

I do not have the software or hardware to permanently disable or "bypass" the Immobilizer but I dont need to as long as I have a matching chip with the ecu.

This is the most modern and advanced Ford ecu that I have tried upto date.
this is a 2003 Visteon black oak st170 ecu that superceeds the EEC ecu's.

I am a big fan of the Oem ecu, Plug and play with no mapping needed but it can be chiped or even mapped via the Obd2 port or a port on the ecu.

It makes a lot of sense to use the ecu if you can get it all sussed out. Painless in the states have been doing this stand alone stuff using all the original kit for years. http://www.painlesswiring.com/webcatalog/featured.php
have a quick flick through their products, they have all bases covered .

st170 manifolds dont fit other zetecs like people say on the net the port postions are way off trust me i know and manifold header parts fetch a packet as i think people are buying them up for itb conversions thinking thay bolt stright up
the rest of the manifold is big and may not fit under the hood of some kits
then there is the odd fuel way the fuel pressure is regulated eletronicly, veriable intake tracts and you will still need to remap to suit exhaust changes
my 10p on st170 all seems too much of a headache for me

im going to make a alloy version of mine later down the line

i am intersted in the st170's knock sensors info for my megasquirt system tho:D

Yeh the ports are around 10mm higher on the st.

The fuel pump should be better for carb upgrades as no return will be needed.

The exhaust is a 4-2-1 design and I know a few have reworked it to fit a kit so no adjusting will be needed.

Yes there is some working out todo, but I enjoy the engine managment side of things.

It will run better all round than any megasquirt can be tuned to do.

there are some squirted 2l zetecs pushing over 190bhp on all std internals now :D

They must be generous rollers as the big tuners only get 165ish with out cams and headwork. I would still question if it will idle like factory and meet an age related emmisions test.

At what price for Ms ? Mtec want £600 for there Ms with a bit of time on the rollers. I havnt looked at uk prices of a proper Ms for a while.

I have installed Omex, Ae, Dta ect on engines, mine and others inclueding a guy that builds busa engines for radical.
They all start at that sort of money PLUS time on the rollers.
I know of a few people that have had multi sessions on the rollers each came away with max power from the start but keep going back to tweek it for around town.

The point of this post is best power for a budget. My ecu cost less than the going rate of an edis4, £29.99 and wont need time on the rollers.

i totaly understand the cheapness and possible fun of what your doing but in my opinion it just needs to be ajustable to suit inlet and exhaust changes needed to fit into a 7 kit also i looked into useing a st170 motor but there is to much in the way of twiddley bits making it an over copmlicated install and i would of had to buy a complete car to get everyting i would need

all boils back to the age old well troden zetec stripped back and aftermarket ecu, exhaust and some form of good inlet

my friend has a sylva striker with a 2l zetec he squirted himself on bike throttle bodies and it was eating type9's even ate a club one
from too much power
had to tone it down come the end and it would pass a cat test come mot time

Right behind you on this one Wasa. :) Please let me know how you get on as Ive been thinking of replacing my Pinto with a Zetec/ ST170 but would only be prepared to go for it if i could use the fuel injection system and ECU.

Getting hold of the right engine, modding the sump, moving the exhaust to the other side of the car - that all sounds quite enough bother and cost without having to tinker around and spend hundreds on bespoke manifolds, setting up bike carbs and rolling road sessions as at that point I'd be better off putting a Cosworth head on the Pinto.
