So you want a non MAF based solution, but don't like the Link for some reason (why? dunno).

SO get an ecu from a 99 2.5 NA engine which uses MAP only (which I found hard to beleive to start with, but it does) and remap it to suit. I wouldn't mind betting that delta ECU can be adapted suit.

Off you go Ecutek, please accomplish....

Thumbs up

Overboost cut ? Knock correction ?
Other than that I would assume the fuel and ign maps could be expanded to suit a 3bar map sensor although that may result in a map resolution issue ?

Maybe not as daft as it first sounds though

my apexi controls my boost, so maybe it is possible?

trouble is, my other apexi controls the fuel, and reads from the maf

It was just a thought Ian, probably a whole lot easier to get a link ecu though.

Even though this ECU may be speed / density, I can't imagine what it would do when faced with above atmospheric manifold pressures.

Maybe not the way to go

Cheers,

I'm not sure it matters.

When I say remap, I mean being able to do things like rescale the MAP sensor. According to the cobb website, it uses AFR target still but with an additional VE map, I doubt this somewhat, as it involves much pointless calculation for the ECU compared to just using injector pulse width.

I don't think anything will come of it, but I would be interested to try. As with all these things, though, might as well get a Link, Gems, Autronic, Motec, Pectel etc.

Why not fitting a proper MAF and remap the ECU accordingly?

I am looking for details from the Hitachi MAF, Audi is using at the moment on their 180 BHP V6 TDi as replacement for the CR@PPY Bosch item.

Yes, this is an option I have looked at, I posted a link to a US company that makes and tests their own MAF sensors, but putting a hot wire MAF into their own machined aluminium body, including one with 210mm inside diameter.
