Excellent work there chill the graph looks really good now. Might have to do a fuel learn on mine as I have only done it once!

I'm convinced there would be more to gain if I changed my exhaust manifold, As I'm still on OEM

[Kieran McC]

I put a Tullett 2.5" with their full system Big gain .I did have to put the uprated fuel pump on, as it ran quite lean at the top end.

[CHILL Gone DUTCH]

I've uprated fuel pump to 255 Walbro And I have Tullett 2.5" back box just need manifold but on the other hand I don't want to go over 260bhp because of engine internals are standard and will be staying that way

My 2.2 NA engine is standard just make it a lot freer with the Tullett manifold

Ok we will have to get you out and about soon,

Wow, 320 ft/lb of torque - am I reading that graph right? That's a lot more than I would have guessed, how much torque does an OEM mapped ECU make for a stage 2 for comparison please? Seems like the power figure is low though, even accounting for power drain due to winding up the supercharger. Surely at 7000 RPM you'd expect something in the region of 7000/5252 * torque ?

Come on Nev, look again. It's a supercharged car for Christ sake.

I don't understand, what have I missed (hence the question) ?

[techieboy]

Torque unit is Nm

[Nev]

Ah, yes, I just read back several pages and realised my mistake.

[CHILL Gone DUTCH]

It's running about 250 ft Ib Which is about 20-30 more

[CHILL Gone DUTCH]

But I'm running a 3.1 pulley instead of 3.35

Ok ive had a interesting morning

after i had been playing with all the ignition settings over the last week or so i have seen some good improvements (see above graphs) however i have noticed the exhaust has started to get sooty. 

so i wanted to prove my theory that the fueling is now running rich after the ignition changes, so i did a other fuel learn session thinking that the fuel must not be right after the ignition changes,

whilst doing the fuel changes the exhausts have now gone back to the way they were,(NO SOOT) 

and here are the results..

 

 

 

red line is average after a run in each direction

[CHILL Gone DUTCH]

And here are the differences from when i started last week to how they are now

 

 

[CHILL Gone DUTCH]

The problem i have now im convinced i will get more from playing with the ignition again 

 

SO TO ANSWER THE QUESTION WHAT CAME FIRST CHICKEN OR EGG?

 

You cant have one without the other.

so the more you work on the maps the more you will get.

but you cant have 1 without the other

I really need to get a new job before i kill my car

Diminishing returns. Yes, more adjustment to timing followed by fueling refinements may help, but since you're limited in power by the con rods what will you do with the gain?

It depends on where the gains are im no confident i can put the power where i want if there is anymore
