Hi

I am looking at getting my series 2 converted to EFI. I have recently had a full engine rebuild stage 2 T3 turbo and newman cam. I am already aware there are alot of advantages to converting to EFI but was wondering will this improve the performance of the car by much.

Any help will be much appriciated

Yes it will as you have alot more control over fueling, ignition etc...

 

I have just converted to EFI, currently at my relatively low boost performance isn't dramatically better however it does give scope for future power hikes beyond the reaches of MFI.

However,

It starts every time
Power delivery is smooth and even
Fuelling is safe spot on all the time
LOTS OF TOYS (launch control etc)
Its much more economical

Generally every thing about the way the car drives is better.

Do it you won't regret it!

Rob,

 

I'm converting to megasquirt, looking forward to getting it running, I best get some money spent soon, could just do with moving most of my cossie management on to save dipping in my savings.

 

thanks for the info it sounds like it will be well worth it once its done.

 

My efi converted runs 52mpg (4,5litres/100) when cruising highway.
Also over 250bhp reliable power. Highly recommend !

 

Antti - Thats wicked fuel economy!

Studabear - Why you ditching the cossie for MS? What are your reasons?

 

52mpg !! What are your cruising AFR's and spark advance please Antti?
From the factory they only did around 30mpg so thats a 73% improvement
I only get around 35mpg at 14.7:1 AFR and 35-38deg of advance.

 

Im selling most of whats needed for,efi cossie management if someones interested for bit of a bargain price compared to how much it would cost to collect it all etc

 

My measurement style was like fill up until petrol pistol first clicks and stop. Then drive to other city and fill up with similar petrol pump. My intake manifold has been matched to head and my head is modified too. Car weights 930kg with spare tyre.
AFR 14.5-15 and 42-45 spark angle

 

Your AFR's are similair, maybe I should test mine again, I'm sure it was only around 35mpg.
Thanks!

 

I've had a lot of problems, I'm sick of it, I don't trust it anymore, with ms I will have a new ecu and loom, hopefully better economy on motorway.

 

Oh ic... Glad im looking at the MS route for starters then! Esp if ppl like Antti are getting around 50+mpg at cruise, bring that on!
