S60 2.4T 200bhp AFR befor and after remap

[fassi1]

Hello everyone
Planning to remap my 2.4T what could give me about 30bhp extra.
Before doing it want to make sure that engine is running fine.
What i've noticed is that in hard acceleration AFR stays in between 14.2-14.5,
lambda 0.98-0.92. I have factory fited wideband O2 sensor and ECU stays in CL all the way up.
Is that correct AFR in hard acceleration for this engine, which is B5244T3.
I bought new MAF, there is no faults, fuel trims seems to be ok, O2 sensor switches (avg 1 at idle, AFR 14.6-14.7)
Planning to visit HLM, but before that i want to make sure that there is everything fine with the engine.
Many thanks.

Not sure about your readings but your engine has major potential depending how deep your pockets are

To be honest i spoke to 2 Volvo specialists and no one gave me satisfying answer, looked like they have no idea whats correct AFR for this engine.
If thats correct AFR its possible to achieve quite a lot by remapping the ECU which means to get the engine running rich lets say AFR about 11.
As far as i know max i can get by remapping is about 30-35bhp and 60-70NM of torque.

Well, from what I've learned here, with a bigger turbo, bigger injectors and then a remap (plus a few other bits and bobs) you'd be looking at a 100hp increase. Like I said, depends on your budget. Hamish at HLM will be able to give you a definitive answer regarding your readings. From what I've read about HLM, they won't just throw a map at it and send you on your way.
I'm hoping to head up there myself, funds permitting.

My S60 is FWD so im not sure if its worth to put so much power on just 2 wheels. i reckon 4WD would make sens.
Definitely will give this guys call, very interested what they gonna say about AFR.

It's daft to get a 2.4 T and tune the arse outta that.

You'd be better off just going with a remap and enjoying 230bhp of lag free surge

or get a T5.....


you'll be ok up to about 350bhp if you get a quaife... any more and it could get interesting... depends if you like getting a workout when you drive or not

yours is a low pressure turbo i would say but them afrs seem to be on the lean side to me but when you go to hamish at hlm he will sort all that out for you and the remap will sort any other issues out with the car.the 30 bhp extra is very conservative they normally produce more.and because you are running a small turbo the will be no lag and will go like stink mate.get the map done you wont be disapointed.also hamish always does a run on the rollers before and after so that will show the genuine afrs the car is producing before and after the remap.

Wouldn't a better turbo and map turn it into a T5 any way? The older T5s are 250bhp with a smaller cc and a dull map (i know) and an S60 won't be as lairy as a S40 with with the same power due to the extra weight and wider stantz.
I recon, after the remap, the bug may well bite .
Above all, enjoy her mate, you gotta nice little chariot there.

they are not the same engine mate but they do map well and pull like a steam train due to the small turbo.i had a v70 2.5lpt and standard the car would do a quater in 16.2 just after a remap it did 15.2 standard power was 193bhp and remapped power was 240bhp but more alot more torque than a t5.it was a very quick car mate

[fassi1]

I must say this engine loves low revs, so much torgue from standard.
Remap should make it more fun.

[smithy]

yes yes yes lol

I meant the 2.4 block itself, being very strong (I'm presuming the block is the same?), given the right tuning they can chuck out serious horses depending on the size of bank balance and size of yer balls lol.
Sertainly not trying to say that a remap alone isn't enough, more singing the praises of the Volvo 5 pot

[smithy]

i agree with you mate but i think they are different engines mate

[M-R-P]

I was under the impression the block, head, and various other bits were the same as a t 5. I won't risk arguing about it cos I'm still a newbie and don't wanna get shot down lol.

to be honest mate i dont know ether and know about the 2.3 t5 and pre me7 engine boxs etc ,all i know is the 2.4t5 engine is the strongest volvo ever built.but still not as strong as a redblock though lol

[M-R-P]

You and your red block!, not gonna give you any grief about it 'cos It's luurvely!

Even though it is a measly 136bhp.......

137 bhp and will run for a million miles that has been proved so i know ive chose well lol

Tell me about it, wish I had a redblock. Just found out my headgasket has gone (3rd time now)
