Frank uses a lotus ECU remapped by Charlie these days.
Pricing should be more than competitive…10psi=300bhp
Frank, would be very interested from a quick read of this to get the exact details of what you’ve done to get the power. This months project is to up the power on my 240R. Any and all help very gratefully received!
Well for starters you can just change your air/air into an air/water and pick up 10-15 hp without any mods…Up the boost and retune the ECU…Keep it around 10psi and you will fly…
Komo tec do this by putting a water jacket around the std lotus item (…bit heath robinson i know) they quote 250hp for the std S just by doing this and optimizing the ecu map to take advantage of the cooler intake charge.
Not convinced by this, think the jacket around the intercooler seems like a bit of a lazy solution. Should be able to fit a charge cooler that is a lot smaller and lower (like Franks) also where do they send the hot water to? Is there a radiator in a side scoop?
I agree, enclosing a air to air cooler in water is not the most efficient way. But probably the most cost effective as all S customers already have the air to air cooler.
They pump the water to the front like Bemani, were they have a radiator.
Wasn’t quite sure in which thread to post this best, but on the topic of ECU remap - Bemani now offers a remap for MY04 and MY05 models that lowers the cam change from 6200 rpm to 4600 rpm. Bemani upgraded cars as of MY06 all have the identical cam changes as Exige-S and 240 models… Thought this may be of interest for other Bemani owners and potentially others interested in a remap.
Thought this would be of interest particularly for Jamie… sorry to hear your red beast is gone, mate!
Cheers Phil
Thats good news! Will let the new owner know!
No worries! Was quoted that the lowered cam-change gives around 10 Nm more torque lower down (I’m guessing around the 4600 rpm mark). I might test drive one soon and see what it’s like, though I will probably hold off as I quite like the kick at 6200 rpm. We’ll see though!
Cheers Phil
I always felt that I wanted to change gear earlier than the red line but did not want to drop off the 2nd cam - the car is faster if you use the torque band instead of the red line. This would be the solution!
Jamie, excuse if I’m a bit confused by your comment - most of the power, regardless if the cam change is at 4600 or 6200 rpm, is at the top of the rev range. On a MY04/MY05 car, maximum power of over 260bhp is reached above 7500rpm and doesn’t drop off until around 8100 rpm and even then, it’s quite gradually so the there’s still over 250bhp available. It would be very interesting to see a graph of what the lowered cam-change, but I suspect, there would be a spike at around 4600 rpm by about 10 Nm and therefore more power. Maximum power would still be at the top of the band though, making it the quickest when reved hard.
I see the biggest advantage of the lowered cam-change to be in in-gear acceleration while in a higher gear or while accelerating in 1st gear from standstill (more torque quicker available). After that though and when reved to the limit, revs would never drop below the 5800rpm mark anyway. At that point, both cars should be equal in power delivery…?`
Actually, I would have to ask Bemani, but this ECU update probably doesn’t make the car any different than a > MY05 converted car. I did drive a Bemani MY06 last year and the car did have a lot of power above 4000 rpm. It was also very linear in power delivery, if even a bit underwhelming in feel.
Anyway, just my 2 cents…
Cheers Phil
PS: Ever receive my emails? One about the enquiries on the 300bhp upgrade and the other a few days ago if you had ever received that one?
Hi Phil
I felt and Freddie K confirmed that exiting corners on track is best done using a lower gear and using the torque. I also ‘felt’ faster using more of the torque and less of the top end power. The Bemani kit (and the Eaton M62) are all about the torque not the power and to me the top end almost feels breathless in comparison to the midrange urge.
But I felt the 2nd cam came in rather clumsily right in the middle of the sweat spot.
I have been abroad (and still am) and emails have been a bit random on what I receive and what I don�t. Please send the email(s) again and I will turn off my spam filters and hopefully the will do the trick.
cheers Jamie
