it's lasted to 108k as standard then another 1k as stg 1.. but just getting smokier and smokier so i'm getting it rebuilt over the next few weeks to a higher spec.

smudgerz

When i had mine it had done 138000 miles, stage 1, was a bit tappety when cold but was still going strong when i sold it. If i had kept it a rebuild would have been on the cards sooner rather than later.....

Depends what you mean with a rebuild, never had any major damage but have replaced all valvesprings once after one of the springs snapped.

0 rebuilds in 14 years.

foreigneRS

most 'rebuilds' seem to have more to do with replacing things that have broken due to lack of maintenance or faults or poor tuning rather than just wear (and poor tuning can greatly accelerate wear - overfuelling, thinning of oil, then lack of maintence in oil changes and you've got bore wear or a spun main bearing etc).

i've rebuilt 2 yb's due to bore wear and piston ring and side skirt wear due to previous owners using shit chips. if everyone used a proper chip with closed loop fuelling, rebuilds would be a lot less common

my car....guzzlers old one

102k, still on original engine diffs and gearbox



difff and box are a little noisy though

People dont seem to realise that teh chip is often the biggest cause of accelerated bearing and bore wear in most YB's.

Instead they like to shout;

gingeRS

so if i got a new stage 3 chip for my saff, could i expect more than the 206 miles i just got from a full tank on my car? mostly round town driving

foreigneRS

gingeRS

just a bit - get a closed loop setup and you also dramatically increase engine life, reduce the need to change oil as frequently etc.

May be worth popping a topic up and asking owners what they get from their closed loop setups, there are quite a few on here now. Be more accurate than wondering whether to believe my sales pitch i guess.

55lb injectors(600cc) ,stu's closed loop set up ,can see 350miles from a tank,

this is an off the shelf chip

best thing i have ever done

JTECH James

iTrader: (13)

and i know richie B9 kOS ,drove to stu for a live map on 85lb injectors, used two tanks from plymouth to blackpool, and three quarters of a tank home on closed loop

gingeRS

is this the closed loop set-up and a new msd stage 3 chip?

i got a price for stu for the closed loop, but was unsure if that includes the mapping chip as well or not.

its currently got a power engineering stage 3 chip in it and fuel economy is very poor

when i bought my 3dr over 4 years ago the egine had just been built to stage 3 spec and had 339 miles on it. I had to run it in. That engine lasterd me 2 years and did get used to its potential.

It eventually expired playing with a motorbike on the motorway, but up to this point it had been totally reliable.

Bought a another engine from Ryan when he broke his moonstone saff (its a harvey gibbs 400 engine) and that has not had any issues since going in - that includes about 4 trackdays too.

Maintenance is the key

foreigneRS

what do you mean by expired? melted piston or what?

not only maintenance. mapping plays a big part in reliability, as does component selection and matching when you are talking about upgraded engines

JTECH James

iTrader: (13)

its more than stage3 im not sure what stu classes it as, but it runs siemens injectors with a closed loop chip.

Closed loop prices and info here to clarify:

Rory - it's this simple. Get Stu's closed loop setup.

No ifs and buts - just get it. You'll save yourself the money on fuel in a few months...

xr2i-carl

obviusly with a high than standard boost car more fuel is needed and subseqent borewash is a reality

thas why you chnage the oil and filter more regulary

R4N SS

iTrader: (6)

it melted as i on and off the gas trying to get the bike to move outta my way





agree that mapping is also very important. One of the things many people overlook when upgrading and simply chuck a chip in that is not meant for the engine spec

Stu @ M Developments

iTrader: (12)

Absolute 100% garbage mate. Totally and utterly.
There is no need to ever inject more than the CORRECT amount of fuel into the airstream and this doesnt really change at any power level.

In fact, as a ratio, we tend to run LESS fuel per lb of air than an OEM does in teh first place as our engines are more efficient. The Focus RS is a great example of that.

foreigneRS

not nice to see

so what are putting that down to? lack of maintenance, component failure, mapping? must be a reason for it.

gingeRS

i know rich, but as an avid forum user, i find it important to whitter and ask questions and talk about things for ages, before doing what i should have done in the first place and picked up the phone and ordered it.


i get paid in 2 days so i WILL be ordering this very soon. along with my new pc

still unclear about the prices though

Stu @ M Developments

iTrader: (12)

That can only be my fault so here goes:


You need to have if you dont already:
High Quality Bosch Lambda Sensor. Ł80
Installation of Lambda Boss into downpipe. Ł40
Wiring of Lambda, heaters & signal into Ecu. Ł50
Hardware Encryption Key for ECU software. Ł100.
Closed loop Map for your ecu, priced as follows:
Ł150 (Up to 803s) Ł250incVat (400s / 403s / Siemens 55lb+)

The boss and wiring can be done yourself if you are buying it mail order obviously.

gingeRS

cheers stu

its just me being stupid, as i have a 1992 with lambda, can assume its a L8 ecu?

the thing i was wondering wasdoes the closed loop map, the same as a stage 3 chip? or is it totally seperate.

would i be right in thinking if my car is L8, with lambda already installed, i can go closed loop for Ł250.

i was just unclear as to when it was in closed loop mode, it would be your chip and when it was in boost mode, it would be the stage 3 chip

if you get me?

Stu @ M Developments

iTrader: (12)

Sorry, didnt realise, in that case you need the closed loop chip and key at Ł250. You can sell your old software on Ebay as its no longer required.

The ONLY thing you need to check is that you have a standard weber board in your Ecu and not a Pectel derivative.

Fudgey

iTrader: (4)

while on the subject of closed loop, im guessing you cant run this with ALS as it will kill the lambda sensor.

and closed loop needs the lambda at all times to work, so its one or the other lol

Rhys

If your car is properly maintain it should go for ages. I only rebuilt mine because a valve seat came out Though it only bent a valve a just slightly marked the piston. I culd have patched it up and it would have been fine. Though i made it an excuse for a total rebuild to 400bhp. But tbh it was on excuse to do that as i could have patched it up for Ł300 max and she would have been fine agian. and thats in 30k miles i suppose as i think i had the car at 60k and done 80k ish when it happened.

gingeRS

my ecu is out of the car at the moment, if you can tell me what i am supposed to be looking for i can confirm it.

then, as soon as the missus car is fixed, i'll post you it for the upgrades, as my soldering isnt too great

Stu @ M Developments

iTrader: (12)

Take a picture of the small board inside and i will let you know if its ok, thats easiest.

As for soldering, no need pal, it plugs right on in.

gingeRS

SOLD

will take a picture this weekend, then if all is well, i'll be on the phone next
week to order the closed loop setup

will be interesting to see if i can get 300 miles to a tank as that will improve my fuel econmoy by 50%

will also be interesting to see if your stage 3 chip is any different to the one thats in there at the minute....and you can finally tell me what to set my CO to

Stu @ M Developments

iTrader: (12)

Done deal, and i will also do you a nice pre winter discount on teh chip pal.

lamb chops

Not sure if im being silly but dont the later 4x4's come with Lambda control already? whats the diffrence with this and closed loop?

Can you also run this with air injectors Stu?

Andreas

Dunno about town driving but I got 435 miles on one tank while using Stu's closed loop chip during the winter. I did drive like miss daisy though.

foreigneRS

took the actuator off the wastegate and held it open with a spring?

matt p

After going to P.T.S

They have a name round here PERFORMANCE TOILET SYSTEMS!!!

Ive heard some horrendous (sp) horror stories about there work

bigad4x4

And i have too

My cossie engine lasted 94k and started to tapp from the bottom end

so i had it rebuilt before anything major happend to it.

Now done 1600 miles on an Andy Fisher rebuild

DENNIS

my engine had 48k on it when i took it out for a rebuild ( 330 bhp ), not cos there was any thing wrong, but cos i was upping the power to 450 bhp
i built it myself with good parts and was set up by some one i trust, other than a set of blown plugs ( because of a spilt injector seal ) it has been as good as gold for 3k ( don't use it much lol ) with regular maintenance they should last, i work for a main dealer and i see new cars with as low as 30k on them needing a rebuild due to the customers service idea ( lift the bonnet when it don't start or there's a rod sticking out the block lol ) yet i see the same engines doing ni on 300k that have been looked after!!!
i am interested in the closed loop system although i do have ALS, will it still work on this set up stu ??

xr2i-carl

stu surely when i said that i mean for a normal chip say a 195 or A old chip used on a cossie back in the day not a specifically written chip foran engine
am i corrrect or still smelly garbage???

just i read in a mag from 1992 when people like collins had already tuned up the escort cossie and commented that there was so much borewash if not serviced oftenenough there was big clearances after only 20k


carl

gingeRS

interesting question? have always wondered what the lambda sensor was for, if it isnt originally being used for as you described???

Stu @ M Developments

iTrader: (12)

Hi,
Yes the late greentop was closed loop as std, but obviously only worked with std injectors, once you swopped the program out for bigger injectors it didnt work as the algorythms addressed different memory areas for a 3bar map sensor and thus you had a car that would run quite high boost at lambda 1, so the old non green programs were traditionally used instead. I addressed this problem and have it working perfectly up to 1000cc. The bonus is that these cars are fully wired and equipped, so you just need to pop in a decent program and you are away.


Yes, but lambda life will be affected by your ALS. A sensor shield may be of use.


Just bad tuning mate, i can do you an off the shelf chip for engines up to about 500bhp in injectorsd up to 1000cc that will work just fine, no borewash risk whatsoever. The bottom line is, these people didnt actually know what they were doing with the programs and couldnt change the low end parameters, there is no other explanation.
