Been waiting for these to hit the mat!

The absolute perfect ECU for a V8!

The perfect AJV8 solution! Can't wait to get building!

On the website this evening!

An early 900 turbo, 1979 to be exact.

Such an awkward looking car by today's standards. Quirks everywhere. The windscreen is so heavily wrapped, something again these days is just a thing of the past.

Tommy of TR Autos brought this over for us to look at a few bits on the Dyno. He's a fountain of knowledge on any Saabs ( I can confirm, I've told him he is a sick man!) letting me in on various quirks of the early versions! Jackshaft for the water pump for instance on the early 8v engines. The gearbox arrangement feels odd too if you've never come across it!

An old K-Jet system sorting the fuel delivery, and ultimately causing Tommy's visit!

Fantastic car, even if I do immediately try and turn these damn things on using the key that's not there! 🫢🤭

Cool-as-f**k-ometer is all the way around to 11.

Vauxhall Chevette 'HSR Homage' F20C powered.

Not a common sight these days, a Chevette in general. They were certainly more commonplace back when I first started driving. Whenever I get a common 70's car on the Dyno, I'm always amazed at how small they are. I literally had a 24 plate Aston Martin DB11 on the Dyno yesterday, a modern 2 x seater GT car, but the size difference is phenomenal. The Chevette, even with it's HSR panelling, felt miniscule!

Funny how we remember things differently! Or maybe I'm just old!

This little car is well known in the community, from what I can tell it's been built to a fantastic standard, and as I'm lead to believe, is built to HSR specs. It's fitted with a stock F20C Honda S2000 engine, with a set of Jenveys, and a dry sump system.

I'm always a fan of the small details in builds. When the small details are correct, it usually means the rest is, and I won't spend my day tracing wiring faults or reattaching hoses in some manner.

79' is a great year!

Andrew, the current custodian has some plans for some potential competition driving in the old girl. Along with coating some of the parts with Cerakote! Andrew owns and runs Amitec - leaders in preparation and application of coating systems, and the quality of the Cerakoted parts on this car are testament. 😉

Great to see you today Andrew, can't wait to catch up soon - he's promised me a couple of laps at Combe in the car.. and now it's in writing! 🤣

Anyway, howling away, as it should be

Another Maxxecu Race Gen 2 harness built up for Tom & Jack at Swallows Jaguar - Swallows Racing

This is a concentric harness, with Autosport bulkhead connectors.

Destined for something really fun!

It amazes me how many hours these sorts of harnesses sup up. Moving from the CMC to the Superseal was definitely a good move from Maxxecu / Maxxtuning AB for the gen 2 units.

Paddle Shifters on a Budget for your aftermarket wheel?

I video alot of stuff, and rarely do anything with it, as I'm useless!

But heres my take on some paddle shifters. Can be made to work on pretty much any aftermarket wheel with a boss. Uses the M3 / M4 paddles. :-)

8HP, DCT, naturally Maxxecu

Massive thanks to Aller Engineering SW Ltd for always looking after us, and never questioning our Sanity!

The Jaguar AJ33 and the VVT!

The VVT control for the AJV8 comes up quite regularly for me. I've had a couple conversations on the phone this week from potential clients, both interested in fitting the AJV8 into a landrover based beasty of some description.

Both guys telling me that the VVT on the AJ33 makes no difference to power, and it's just there for emissions. Often times it feels like I'm beating my head against a wall. I get arguments for 'keeping it simple', or 'it's easier to just not use it'.

I meant VVT is pretty solid these days on aftermarket, it's literally a couple solenoids, and a pair of position sensors. Seems mad not to use it in my book.

A couple of weeks back I took the opportunity while tuning one, to lock the cams (via the MaxxECU) at 0 degrees and do a run, then with optimised VVT and did a run. The runs were back to back, within a couple minutes of each other. Power & Torque displayed at the wheels.

It's hard to argue with the 'No more power Gag', but I know I'd prefer the bags of extra torque left on the table right! It's not just for a few hundred revs either!

PS. The Supercharged AJ33S behaves in the same manner!

Naturally this is just WOT, and naturally in a race environment. There is no argument from me that VVT has an impact on the emissions, ultimately it should be calibrated correctly throughout, but to purposely not worry about emission, and indeed stump yourself of 40ftlb for the majority of your WOT seems utterly mad to me.

Let those cams swing! Let those free ponies loose!

Congratulations to the lads at Yellow Peril racing!

Jordan and his team completed his AWD truck this season, running on the Maxxecu Race powering his N62 BMW engine. The Maxxecu is also running his 8HP gearbox. (Naturally!) 🤜🤛

You can hear this beast on the Dyno further down the page. 😍

They were rewarded with 1st in class in the British Cross Country Championship.

Well gone guys, great to be a small part of it. Long may your success continue!

Pete's Audi S2,

Proper build, G30-770 Garrett lots of engine goodies.

Glorious noises as you can imagine!

Naturally Maxxecu, lots of really Naughty Launch control noises, and a whole lot of 5 cylinder big turbo noise making my day!

We ran out of fuel pressure sadly! Pete will be back with more upgraded parts, so we can let her have the full extra two and a half atmospheres.

Good to see you mate!

Many moons ago, and I mean MANY! It was the early 90's. Lots of interesting stuff going on the general Automotive world still. Most of all, (for me anyway) the Jaguar XJ220. A car that still looks absolutely f****g amazing now, was built and sold. There were posters on my wall of this thing, and we used to play 'Jaguar XJ220' on the Commodore Amiga. Life was epic.

Fast forward a day or two, and I started racing a Jaguar. Before she got banned, we raced on a grid of classic Jaguars. Many of these had classic liveries. 'Castrol', 'Becks' and the likes! I have as you may know if you follow the page, an X100. So, for me, there was only one option. My favourite car of all time once raced in a Martini Livery.

Hold my Beer!

And so Senderella ended up with very rarely known XJ220 Martini Livery, as a Homage. (I can't stand the drink!) 🤣

Fast forward a few more evenings... Swallows Jaguar - Swallows Racing and put on a coffee morning, in which the absolute legends at .trust drove an XJ220 to take part. Yes, they drove it from Gaydon to Somerset. It's a testament really to the things! Id have loved that job!

Regardless, I didn't move very far from this car (and the coffee machine, naturally) all morning. I was lucky enough to move my car next to this legend and get a photo or two.

Made my absolute year to be fair! I'm a happy boy!

Thanks to all the guys that made this happen, the coffee and cars meets they've started doing are absolutely great, and I'm not a car show guy, like, at all! 🤣☕☕☕

Cosworth YB Harness for Mk2 Es**rt, with MaxxECU Race

I seem to be getting more and more orders for these packages. I try to allow them to be as customised as is possible.

Stevie, sent me down a 'pattern' of where he'd like his ECU located on his Mk2 es**rt, along with various other sensors and the like for his YB Converted Mk2.

He's opted for fly by wire, modern injectors, K20 Coil on plug conversion along with various sensors for protection. Knock control / Oil temp / pressure and so on.

I've left an Aux plug in the engine bay for future upgrades, along with plenty of I/O inside the car too!

Stevie asked if I could sort a fuse box for him too, in order to make the installation as easy as it can be. I've modified the MaxxECU off the shelf fuse / relay box, so that all the new systems are powered by new fresh harnessing. Fuel pump & fans are powered by this fuse box. Plenty of labelled cable to get around the vehicle!

I've also added in a few extra wired for his guages & cluster. Hopefully it'll make his life installing the system nice and easy!

Another YB Mk2 safely under the instruction of a MaxxECU!

Thanks for the custom Stevie, I look forward to getting logged onto this and getting you up and running. :-)
