For starters you can't be unhappy with that result Dunc...
Well done mate... the only way is up!

Heard that Simtek for mine is 6-9 months away so another solution is being sought to give me strong and stable boost control.

Greddy Profec B is top of the list at the moment

.... unless someone wants to sponsor me a Motec

Not desperately unhappy no, 438 with that boost profile is remarkable, shame I couldn't get it under control to get some proper figures further up the boost scale.

What about a Prodrive 3-way BCS or one of the aftermarket 4-way BCS'? Would none of those not suit your setup? I can't Remember if you're still running a Denso ECU.

Got a prodrive 3 port on there.

I am hoping that the map just needs work but I may be struggling in vein and for the sake of a few quid it is easily solved with an aftermarket controller.

Why don't you ask around on RomRaider, perhaps one of the regular experts there knows the score??

Just a thought

I meant to say....did you alter MAF and Load scaling?? I read on there they can now alter MAF scaling beyond the normal 300 (350 - 400 now).

Stupid question probably as i'm sure you have all the bases covered :thumb:

Good stuff Duncan

As you have found out you will need a slightly different boost profile for the rollers compared to the road, only takes a couple of minutes with Simtek/Gems etc. Not so easy with the stock ECU.

I was on the rollers with our new 'baby turbo' this week, 411bhp & 406lbft was the outcome... not bad for a non AVCS 2.0L :twisted:

Jase.

i use the same boost profile on road as i do on dyno,depends on how you run it

Waaaaaaaaaaaaaay over the std 300 grams/sec limit now

I am much happier to figure this out without seeking advice from people that I dont know.

The std ecu was designed to do a certain job and it does it very well, it can be stretched to do other jobs or get greater performance but is always going to be a compromise. I am sure that given enough time, that I could get the std denso ecu to do what I want, but for a simple short term fix I think a boost controller will just take that worry away.

Ultimately though, speed density and live mapping are the way to go - it just saves so much time mapping.

FFS Get a decent ECU on it Duncan. This is painfull to watch :lol:
