Default AJ6 Engineering - SE ECU Large Throttle Kit

Hi All,

I have been in touch with AJ6 Engineering in the UK.

I am changing to a 3.54 diff as the long legs of the 2.88 are at the wrong end of where I enjoy my power. (I often run on the open road (110km/h) in second gear and fuel economy is not an issue for me)

I am about to push the go button on the SE ECU Large Throttle Kit, but have seen a couple of conflicting reviews that I would like to clear up.

My guess is that these reviews are few and far between and everything will probably be fine, but wanted to see how many of you are doing a similar thing with Rogers products.

He appears to know his stuff and seems to have been in this business for a long time.

Has anyone had experiences (good or bad)? I would love you to elaborate on any knowledge you may have.

Thanks all.

Craig

I've used two of his Superenhanced ECUs for the V12s and, plainly, they worked as advertised

Cheers

Open up your exhaust and intake or these mods won't really get fully realized. The CATs and center mufflers are awful, the intake trumpets to coffee strainer airfilter might aswell be a noose.

AJ6 is one of the only reputable sources for actual enhanced parts.

Thanks Vancouver...

Exhaust is already opened up. 2.1/4 inch pipes all the way back via straight-through mufflers.

Never had cats installed. so all good.

Cheers!

The AJ6 stuff with transform the car. You need the ECU and the larger throttle bodies. I have had it for 18 years now and it is just terrific. Bywater is the most knowledgeable person on the planet about the V12, you will not be disappointed.

He's getting on in years so if you want his expertise and modifications, sooner might be better than later.

It is in the trunk on the right side behind the carpeted panel by the battery. Kind of tucked away in the "flying buttress". I believe it is attached with 3 small nuts, the large connector, and a vacuum hose. Once the carpet panel is removed you'll be able to see it if you stick your head into the right side of the trunk and look up. Just another instance where this car demands you be a contortionist!

Thanks for this post. I've been considering this kit for a long time and I'm going to pull the trigger asap since it sounds like it's not going to be available forever.

Norman Lutz is building my engine and I asked him about the large TB's, his response was don't waste your money the stock ones are good for 500hp EACH and are NOT a restriction, larger plenums would be a better option. Then optimise ignition timing for 95 or 98RON fuel, the stock V12 (Lucas ignition) here in Aus is tuned for 91RON.
