AUII_Forte

Hey Guys,

I have a 2000 AUII Forte with a K&N panel filter, 2.5in exhaust and Genie Extractors. The car feels soooooooo slow until it hits 2500rpm. It goes pretty well in high revs, but I think an Excel could beat me off the line! The car seems to be running fine and doesn't chew fuel or anything, it has also just had the plugs and leads changed.

I thought the BBM may have been unplugged, but that wasn't the problem. How do I extract the fault codes from an AU? Does anyone have any ideas? It's really annoying me.

Daniel

Bar the K&N I have the same mods on my AU XR6. It too is pretty lame under similar revs. But when the sucker hits mid range and top speeds it pulls pretty hard.

The T series intake has helped the throttle response well but low down go in my opinion is crap.

As for the excel beating you on take off. Believe it. I had one and the first gear in it caned (99 x3 twin cam). Even on a quick downshift or two the engines snap violently forward when accelerating. The exhaust system when it was fitted dulled some of that tho.

With a standard falcon you just gotta get past first gear before the excitement kicks in. From then on it's ok.

Can't help you on the fault codes sorry.

Is the car auto or manual?

A possible factor, I think larger exhaust systems increase top end power at the expense of low-end power. If this is the problem, a diff ratio upgrade will be the solution. Ford are idiots for even thinking about using 3.08s with the tall BT-R ratios anyway.

I think the diff has a lot to do with it. The EB was a 3.27 and would eat the AU for breakfast off the line.

It was doing it before I put the exhaust on. Maybe I've just gotten used to it and need more power! It's a bit strange though that as soon as the car hit 2500rpm, you can actually feel the step up in power. It's like when a turbo spools up and kicks in, but on a lesser scale. Thats why I thought the BBM may have been disconnected or similar.

I will be getting a Crow Stage 2 possibly 3 (if I can get away with it without ECU mods) in the next month or so, that may help it. After that an XR6 3.45 LSD diff centre. Does anyone know if the E-series centres will fit the AU?

Yeah I hate the diff! I will be getting a 3.45 LSD asap.

I just think something must be a miss by the big surge of power that comes in at 2500rpm. It's a very very noticable jump in power, surely it can't be normal. From memory the BBM doesn't change till 3800rpm, so it's not that. I got no idea.

EvilChief did you convert yours from auto??

I am looking at doing this to mine, but just wondering how different converting an AU is to an EA/EB. I have converted 2 E-series, so I am confident in doing the job myself, I just want to know whats different. How much did it cost you?

well the cost is much higher compared to teh E series due to the newer gearbox, however as for conversion there is not much diff at all. as far as wiring goes very similar, it all bolst straight up like if u get a complete kit you'll be right
