Ok guys... here goes.
I know nothing about the relative merits of each of the products.
I'm just asking your thoughts of the following.
My choices:
Power FC for Celica 2zzge - not designed specifically for my car, so will end up needing a re-wire to get a few things working... keeps MAF, so no additional cost, and not a lot of downsides to staying MAF anyway. Tuning support everywhere
~1200NZD
LEM G3 - totally wire in, supporting a kiwi company, should do the trick as good as any other, tuning support really good.
~1300NZD
Greddy Emanage of some sort - wire in with the current ECU... results seem to be ok overseas, note "ok", looks to be a "cheap" option, tuning support really good.
~900NZD
Hydra EMS - Havent heard of them outside internet forums, seem to be fairly good, and compare fairly well with the Power-FC for the 2zzge, in NZ tuning circles they seem mostly unheard of... although the software looks much like all the others.
~1600NZD
Unless I can find someone who has dealt with a Hydra before, I'm probably going to stay away from them, even though they have had good results overseas. The others that can do fully variable valve timing(with intelligence (C) )seem to be out of my price range, but more than willing to consider them given a decent arguement.
Once again, thanks guys, you're teaching me a heap.
