A stage 1 & a half?!

[Mr Whippy]

How about 140 for a stage 1.5 with water methanol injection but no intercooler? http://www.hdi-tuning.co.uk/ecu-remappin...ermap1.jpg

I quite liked the way it drove, however the water pump costs more than it does to do a stage 2. Easy though.

Chris Bryn did that about 5 years ago iirc, and I did the remap for it.

It used a nice technique whereby he'd turn up the boost on an MBC and the raised MAF would expose the fuellings which would otherwise be dodgy on a stage 1, but at that point he'd turn on the w/m.

So you'd turn down the boost when w/m ran out and it'd not allow those big fuellings.


Unfortunately he never did refine this and fit an FMIC and hybrid turbo instead which really was a better solution.

Imagine if you ran out of w/m and forgot to turn the boost down or something hehe.

I'm not sure if there are any other really nice ways to turn down the fuelling. I know the EDC15 BMW's run EGT limiters, maybe some way to enable one of those?! Somehow.


Gah, it'd be just nice to get the SDK and recompile a new software for this engine hehe

Hmmmm

haha, there are far too many people quoting well over 300lbf.ft, it's just not really plausible when TB had gears stripping at 420 Nm didn't he IIRC?(310Lbf.ft) And that was with a gt20 VNT!
I'm going to have to stick a VNT on one of those when I get around to it, after setting up the 1.6 HDI from the bottom up I know more than one human should know about turbo control systems. I dream about it now

I agree... I've seen a few questionable dyno results with inertia dynos and corrected figures (double whammy of questionable figures) showing way over 300lbft... but all the evidence from past experience suggests this isn't really possible.

In the end a clutch is designed to break before the gearbox (or slip), but given we fit these crazy clutches we then need to protect our gearbox through correct tuning.

Given others have already said they've had problems at 300lbft+ I think it's reasonable to say that is a good place to stop.

Also from the shapes of the torque curves and the really short gearing I don't see much benefit in all that torque any way. Wheel spin in 1st/2nd/3rd in the dry, probably 4th in the wet in a straight line haha... hmmmm. AND the risk of gearbox failure... not exactly a good long-term plan to tune a car to failure hehe
