Just fitted my "stage 2/195 upgrade" to my OFAC managed Orion.
Beiges, and P1 Superchip... Car runs lovely and bizarrely enough i've had to back 0.2bar of fuel pressure off at idle over the standard blues!?

Anyway, ive adjusted the boost to around 1Bar, which is runs happily most of the time... Every now and then it misfires when on boost, only once or twice and then settles - any ideas?

 

over fuelling, were the injectors brand new and are they 701's? could be leaking as this was what happen to my last efi, or the injectors might not be 701's and too big

 

The injectors have just been "cleaned and refurbed" all are now flowing 240cc/min... They r 701s!
It only seems to do it every now and then?

 

Your superchip wont have a map for the rising rate regulator you use, so I'd guess that once it comes on boost its got too much fuel and coughs it up?

 

Interesting theory... But i doubt its the cause as the reg is an upgrade for the fiesta rst for use with the stage 2 195 chip and the rate at which is rises is what the engine requires whereas the ford 1 at that level doesnt rise at the nessacery amount, but i i'll give it a go.

Need a fuel pressure gauge in the car really to watch it, it its rising at all!?

 

how did they get cleaned ? can they not mess up sometimes cos ive read people avoiding buying them if they been flowed cleaned or summin like that

 

I'm not so sure Roger
As I understand it, at 1 BAR boost the ECU will be doing the fuelling based on the 1:1 (standard) regulator, so it will be expecting the fuel to be at 4 BAR (3 BAR idle + 1 BAR), and on the chip will be an amount of "squirt" for that pressure, whereas with a rising rate jobby, it will have the fuel at something like 4.5 BAR, so for the same "squirt" you will get more fuel than expected.

Pity with the injectors but at least you get them in and running now!
I've decided to skip the stage 2 stuff and go megasquirt over the winter. Will run standard for now til mine gets some miles on it.

 

I toyed with the idea of MS, but i'm gonna stick on the ford stuff for now... See what power i can achieve and then when i get some more engine work done over the next year or so i'll maybe look at MS again.
What your saying about the fuel rate makes sense, i'll look into it. But its been fine so far with the fse reg and alot of other ppl use em. Ive just ordered a new fuel filter and plugs which arrived this morning.
What ofac stuff do you have left over that you arent using? Maybe pm me about that lol?

 

Standard Ford FPR is fine for the 195 conversion and does not require changing. You haven't got an FSE job on there have you?

 

Just seen you do have an FSE. Remove it and replace it with the original Ford item and have it set up and I would say it's very likely to solve your problem. Those things are about as much use as a chocolate fire guard

 

My tuner recommended i get one as they are fully adjustable and provide a better enrichment rate...?
I'll try removing the reg and see what happens

 

Your tuned just sold you shiny shit. Standard one is adjustable and perfectly able to cope. The FSE items are famously bad. Do a search on here as it's been discussed on quite a few occasions.

 

i got the same set up as you mate but have the 1.9 engine and it dont flow enough fuel

does anybody know a way to flow more fuel on this setup bigger injectors ? cant really afford aftermarket management yet although i know this is best route

 

TBF there are mixed reviews on here... I'll try putting my standard 1 back on and going from there!

Just worth mentioning also my tuner never sold me the FSE just recommended i get 1 - so i did!

What other brands are a direct fit into the frst fuel rail?

 

have you checked your plug gaps and what are they set too fella

 

They r ngkr8es or whateva, with a 1mm gap. But after speaking to Stu @ MSD ive gone for some 071c's with a 0.7mm gap, gonna try them over the weekend and see what happens!

Cheers

 

Totally correct.

 

I read my Fast Ford tech articles
http://www.motorsport-developments.c...AF242.tech.pdf

 

sorry to hijack rogeyboy but if the fse one provides more fuel would this be sutible for my problem as i need to get more fuel in when the injectors fire to compensate the bigger engine ??

 

Brilliant, thank you mate, good to know people are benefiting from them as sometimes I just feel like calling it a day as I am super busy nowadays and struggle to find the time to devote to them.

 

Ive read the articles aswell, They make for a good read...!
Im going to try my standard fuel reg today and see what diff that makes, its not so much "missfiring" on boost, its more turbo stall as it boosts up the boost gauge flicks back to zero and then to the boost level... Only over 0.5bar, but i can hold more than that. Just every now and then it turbo stalls!

 

Changing the fuel pressure reg made no difference whatsoever, other than the fuel pressure fluctuates at idle with the standard reg on and doesnt with the fse - so i'll be keeping the fse i think...

Car still turbo stalls as it comes on boost, sometimes i can get it to hold other times it stalls and pops...?

 

boost leak ? are you sure its a 195 chip has the chip slipped or moved did you tape it to ecu sounds like you might be getting the ecu's standard boost cut

 

what a great read that was , but my head hurts now

my frst is running 50psi in fuel prssuire is that normal ? whats that in bar , sorry stu to be a pain but what is the max psi i can run of boost then with my bieges and standard pump with a 195


Ben

 

If there is an issue with the stock item I would be inclined to replace with a new standard one and file the FSE in the skip. You will probably find that the FSE item is actually masking a problem though as this has been reported before.

You may need to stop chasing things about and take it to somebody who can look, it over properly and understands howthe injection system works

 

Could it be as simple as duff spark plugs allowing the spark to be blown out?

 

Well the plugs have been changed and the problem was present both before and after... I intend to try the stage 1 chip at 0.8bar and see if that misses/stalls the turbo with the beiges, if not then i think the chip might be at fault.

Oranoco i know you are against my fse fpr and i do appreiciate the advice but there was no issue with it before, unless the boost increase of 0.3bar has upset it...?

Im keen to cure this issue and then get the car to someone for a set-up...

 

One other thing to add, the chip isnt the tightest of fits and maybe taping it in might help, i will try that tonight aswell!

 

Appreciated mate. Clean the chip contacts with a non abrasive electrical contact cleaner on a lint free cloth. I found with my Fiesta that making a small shin to sit between the chip and ECU helped no end with poor contacts.

 

Tried tapin it in and cleaned contacts, i thought it was better, but it just behaved itself for a minute or 2 but its no diff...
Bizarely the stage 1/165 chip i have works fine with the beiges with no probs at 0.8bar boost it pulls fine no missing etc, but the stage 2/195 chip that should allow 1.2bar seems to be misfiring/boostcutting at all different boost levels on spool up, once the max boost (arnd 1bar atm) is reach the mifiring/turbo stalling/boost cutting stops and it pulls hard and consistant!
Could it be my MAP sensor getting a boost spike before my boost gauge, so my gauge is showing 0.8bar when infact the MAP is getting 1.2+ bar?

 

Are you on OFAB or OFAC? iirc OFAC is unable to read boost above about 12psi. 0.8bar is very close to that threshold. Just a though, sure Stu will correct me if I'm wrong.

Hate these niggling problems, drive you mad trying to suss them out

 

OFAC, I thought the OFAC could read up to 16psi/1.2bar with a stage 2 superchip in as its the ECU's map that limits the boost and the superchip overcomes that?
We need Stu to inform us then don't we lol!

Yeah it a pain in the arse, the car drives really nice with the chip and beiges in aswell! Just problems as the boost spools in!
