You're the best.
Where is Mike based?
Mike I have PMd you
Mikes going to do mine as well when i finished my CF airbox install , yeah!
Getting myn mapped this evening by mike....will let u know how it goes.
Did he come down here to do it or did you go up to him?
He did it remotely carl
I messaged him awhile ago about it but in 2 minds as I'm after a gtr bonnet as well .
Cheers Mike for explaining that, I was going to say that the limiter is 8200rpm.
Not really worried about chasing figures, in the real world my car is silky smooth with no flat spots and pulls in every gear to 8200, well not had the balls to do it in 6th yet!! Lol.
You can see on the graph how nice the curve is also!
Is there a thread explaining the difference between a gsr box running alpha-n and a gsr box running csl software? not the difference in actual driving, more whats involved with the job its self? i.e is it just a remap or a conversion?
The CSL software uses completely different mapping in terms of load points etc..For example the CSL has fuel maps that inject a different amount of fuel at a different time than the normal M3, also uses a map sensor to accurately measure oxygen content entering the engine. Alpha N uses air intake and barometric pressure and RPM. CSL uses all of those plus the main MAP sensor and is much more accurate.
In Lehman's terms
I hope that answers your question.
My ecu is currently with Mike for conversion
I have been running a gsr airbox and evolve alpha N, was a bit oblivious to the csl map sensor and assumed when i bought the gsr box that alpha n was kinda the only/best way - when i spoke to evolve on the phone about the low end and partial throttle hesitancy they told me to drive round it and that's just how it is.......
Now that i'm running a genuine csl box and having driven a mates csl i know it's not right and should be alot better!!!!
I'll get some pics up of the map sensor install and a back to back comparison once the ecu is back next week from Mike
What are the real world performance differences between a GSR CSL Airbox and a Carbon remap and just a Carbon remap on a normal engine with a standard intake?
Who cares it's all about getting that CSL induction sound.
All I know is Your going to see around 360 bhp with a CSL style airbox and remap as this seems the normal figure most are getting on here and according to Mike too
Ditching the restrictive stock airbox and maf and running the much more advanced CSL software and map sensor is going to make the car drive so much better accompanied by much better airflow and a lot more cold air too if fitting the CSL cold air feed to the snorkel
So with Carbons map, we are talking about a generic remap for the E46 M3 and not one specific to the individual car?
Wouldn't one fitted with things like a GSR / CSL airbox, or different profile cams need a more specific map?
So Ive done a fair few miles and a mixture of driving since having this done.
This is by far the best money Ive spent on my car. Great work by Mike
Minimal performance difference.
IIRC Gibbo2005 made just shy of 380bhp with stock intake and Evolve remap (he also went to Evolve as nobody believed the figures were correct, and he put down the same power there too), then he switched to GSR CSL airbox, MSS54HP ecu with CSL sw, TTFS remap and map sensor and pulled just shy of 380bhp again on the same dyno.
380 with stock airbox and maff??? Not likely.
Most std cars are going to put out around 320 of the 338 when new give or take depending on age and condition so no way a remap alone is gonna give you 60bhp!!
360 is the figure with a csl airbox and this seems to be reported by most people who have gone down the csl airbox route. As the csl air boxes have far better airflow and also gets rid of the restrictive maff I can't see how that figure with a stick intake and remap is even remotely possible.
That's more than a stock csl produces!! Lol
As said, everyone on here was saying the same, so he took the car to Evolve and it put down the same numbers on there dyno
Why do you think the maf is a restriction ?
