Wanna raise the rev limiter to 7.2k and was wonderin what's actually involved to do this/costs???? I'm on solid lifters and it pulls really hard to the limiter meaning it keeps hittin the limiter in the lower gears especially! Cheers

 

Don't think you can mate

 

The fuel ECU controls the rev limmit, you need to change some resistors, i dont know which or what for afaik!

 

actually it's capacitors...

the other way is to swap to an s1 fuel ecu, and rewire the TPS

 

I did this on my old s2 got tony from turbosystems to do it.

 

so a S1 fuel ecu will let you rev to 7.2k or does it remove the limit?

so is this a straight swap? how do you mean rewire the tps?

 

It will remove the rev limit totally. I use an OMEX limiter which is adjustable, and gives u either a hard or soft limiter. It makes the car much quicker to launch, as u can bounce off the limiter without the car bogging down.

if you simply swap the sw for an s2 item, u will have no full throttle enrichment, or fuel cut on closed throttle.

Instead of the TPS earth wire going to earth, it needs to go to a terminal on the S1 ECU - essentially it's -ve switching. I worked this out years ago - never understood why more people didn't do it. Can't remember the pin no from memory.

 

According to the info i have from the Bosch manual Fuel cut is a standard feature of the KE Jetronic???

 

Yes it is but if you swap the S2 box for an S1 box, the wiring will be configured wrong for the S1 box making the Decel fuel cut off feature inoperable!

 

Mr chav - which fuel cut are u reffering too?

I'll be most happy to educate u

 

The overrun cut off that the fuelling ecu does as part of its miraculous (!!!??) fuel saving economy.

I am more than happy to be educated

And stop ignoring me on MSN ya c*oont

 

I'm not - i post from diff pc's and my home pc is always signed in - if im there - i'll reply - ignorance is a sign of weak character.

The overun fuel cut IS built into every ECU - but have u considered how the ECU knows u are on overun?

 

Ive just had a look over the wiring diagram and i see the wiring variation, pin 6. Series 2's dont have the connection on pin 6 instead its in with a common ground.

 

THe problem is that u there is no pin in the S2 multiplug. Call me a butcher, but i soldered a wire directly to the ecu pin. It's done 2 years and 40k with no probs

 

so does this mean theres no way of raising the limiter on a S2?

Id be interested to know how if you could, 7.2 K sounds nice.

 

There are capacitors you can change inside a S2 fuelling ECU although capacitors have massive tolerances, and its not something i would advise doing as a DIY job just incase.....

 

so thats the only way?

id be interested at whatever cost......GoTech?

 

After market management is always going to better than KE Jetronic, just the question of can you afford it?

 

moneys no object for my machine

whats my options on aftermarket management?
Names and prices by any chance?

and this might be a stupid question, but getin back to the point, will aftermarket management able me to raise the limiter?

 

With good aftermarket management and a DEEP pocket the sky is the limit.

I don't know much about aftermarket management im still a standard RS boy

Omex is one they're only up the road from me aswell!!

 

any idea on the price?
cheers for the reply mate

also could u look at my other thread? cossie calipers? noone seems to answer. maybe you will know.

 

I have no idea on price, people like Rick, DazC, Biglee etc will know a hell of a lot more than me

Your other thread christ sake dont want much do you

 

haha am i asking a bit much???

 

cosworth management is the route i took...

for all prices and queries get on the site...


www.oddkiddcreations.co.uk

 

not sure about cosworth management.....

Seen a nice big arguement on here before about people criticising how old the system was.....

What sort of price is it for the cossie stuff then?

 

Indeed Cossie management is stone age now, and aftermarket managements are getting a lot cheaper. Cossie stuff was the stuff to have when it was a lot cheaper.

 

click the site link for prices etc matey...

it may b old but proven!!!

 

I never said it wasn't proven.......

 

yea but i cant see the prices on the site!

 

Which site is that mate? Im surprised the regulars havent been along yet to give their opinions on after markets ecu's.

Get some phone numbers and ring round

 

I can raise the Rev Limit on the KE Setup @ 500 revs extra per time

As said the best VALUE FOR MONEY WITH RESULTS is weber management (Cosworth) As the parts costs naff all and work 100%

 

how much would i be looking at Mr Oddkidd?

 

Cant offer services via here mate

 

register on the site geez.... all u need to now and more!!!




well worth doin......!!

 

Hang on a minute!! We have all assumed he was on about an S2. If it's an S1 then it's different!

 

sledge hammer, walnut...

 

A valid point
















(note the S2 in the siggy)

 

That is why we assumed it's for an S2. It may not have been as not all people put their own cars in their siggy...

 

Yeah thats a fair comment i was only playing

Im pretty sure he does have from talking to him on previous threads

As they say assumption is a mother fucker though

 

its a series 2
