do you happen to have another one?

good ol GM!

Thanks David.. but then how would the plumbing work coming off the throttle body at the end of the efi manifold..

Good idea re the water temp sensor :)

Thanks DD the haltech has an inbuilt map which is handy.. I still need to find a decent air filter IAT setup hoping from a wreckers otherwise something else

If you were going to use just map and an IAT where would you plumb in the stock manifold to the map sensor?

Thanks DD,
You're always crazily full of information :)

I found bosch wideband o2 sensors from a wreckers for $25 so happy about that :)

sorry been a long day at work.. got my acronyms around the wrong way!

The Haltech I'm going for has an inbuilt MAP sensor. So does that mean I could avoid a MAF altogether?

That sounds like a better option! inside the air filter and cleaner you say! what model out of interest?

Hi All,
Not too sure about the technicalities of what kind of MAF would be suitable in terms of configuration/capacity wise but I was wondering if a 1.8ltr holden astra MAF would be ok to use in a stock a15efi setup?
Cheers,
Tom
