Have you got a screen shot of the ignition map for a laugh too?

I agree, to help with this the company is based in the west midlands. Hope this takes most out of the spotlight.

May aswell have a guess lol - P J Motorsport

It's Czech Mate

Aldon Automotive?

WENNY

lol nice

SiZT

remember a lad I know took his car there and did 192bhp at the wheels. He supercharged it (only low boost) and on a different set of rollers got 196bhp (I think) at the fly

I'd take a guess at P.J Motorsport as well

Matt Evans

Is it PJ then or not?

Although it does look like a Hi-Tec special map!

Would Aldon really wanna mess with an old rover either?

Thats far better than the ignition map JDM put onto a vauxhall turbo engine recently.
Ive seen several "professional" jobs far worse than that!

At least its got one correct value per row

Thats shocking proper bodge.

pretty please

Aye like others have said can anyone in the know explain how its wrong, "Ie" a basic wording so that for the folk who dont know can understand?

MikeR

They are not in the West Midlands and l very strongly doubt and would be massively surprised if Mark would have done that, so l am unsure what you are trying to achive by your cryptic response other then to start an argument or piss him of,

Maybe l have missinterprated your reply if so sorry but l think it reads the way l have intepreated it...

Mike

fuzzy

was it reyland? i notice on the website they specialise in rovers.

M-Tech Automotive

lol loving the crank sensor...

this is what we do when we are using a 36-1...

First we make an ally braket to suit... (this was on a Porsche 928)

Then we machine and fit a trigger wheel to the crnak pulley...


Thats just us though....

:P

Ok, i've stuck Martins picture of the fuel table into paint and quickly done a few markers on to try and explain it to you guys.

This is purely my opinion i might add!

Ok, in the bottom left corner you have zero load (throttle position & map sensor calculated load) and zero revs (engine speed). In the top right, you are 'flat out' with full load and full revs.

So, you would expect the reference to happen in between these two red lines if you floored it from idle in gear and pulled to the rev limiter.


Now, looking at the values in this fuel table, you will see there are A LOT the same! I've highlighted in boxes the big chunks to clarify...


According to this map, the engine needs the same amount of fuel at 1200rpm as it does at 8500rpm if you look at the top line!

And - on the 2nd and 3rd lines down for the load, it requires more fuel at lower revs than it does high. Admittedly you can find that as the turbo runs out of puff at very high revs, it needs slightly less fuel, but certainly not like that.

So, if we put our expected window of reference in picture one over picture two - it looks a little like this:


It appears that once it's "in the ballpark" - that value seems to be good enough for nice big blocks!

VERY rough mapping, no compensation for the changes in volumetric efficiency the engine WILL go through during the rev range and i would imagine the fuelling is pretty far away from where it needs to be.

I would also imagine that it drives pretty rough too. If plotted in a graph, it would look something like the himalayas! It should be nice smooth flowing lines...

Hopefully that will let the 'less mapping familiar' in on things...

MikeR

Learning from Stu mate, nice explanation cheers

Mike

Right so the table shows that its going to run mage lean on top, hmm dodgy stuff lol

BRIGSPORT

Thank fook for the explanation!

Big Will_

No. The slight leaning of the mixture isn't the (major) concern here. It's the fact that there are such huge blocks with identical numbers in. The numbers should be different in each cell to suit the fuel requirements of the engine under the conditions

Good explanation Will

Made him up a basic bracket to hold his CPS and have mounted the trigger ring on the inside of the pulley, will get it running tomorrow and get it mapped.

Martin,

What sort of CPS is that? Looks alot better than the Ford OE ones we use... flying cable

Matt

jammerrs

thansk for the explanation

better the devil you know

Looks Like standard magneti marelli Ford sierra cosworth fitment or fiat/lancia.

Big Will_

Agreed! And judging be the white insulation on the wiring its not in its first flush of youth either!

All the OE items had white insulation, all the aftermarket replacements have black

better the devil you know

Very well observed Will, around 400 ohms on a resistance check at 20 degrees C ?

to narrow it down a bit, can you start some sort of hangman type of game for us?

looks like a 5 min map to make it feel good when showing off to the owner giving it beans.

Big Will_

And for the next time your multimeter gets eaten by a dinosaur... There is this option

paz_S2

better the devil you know

yep i agree, but cant use that when the sensor is off the car when the customer bought it in for you to check because it wouldnt start

Big Will_

True! But in 2 years that's never happened to me

Karlos G

Will, if I come in tomorrow can you test my CPS please??

Big Will_

No

I've got a record to maintain
