Aftermarket ECU witch one?

[bababoom]

maybe after one of these soon and it's something I've never looked at before so know nothing about them.
ie how they work or how much they cost?

[hfstuart]

The cost depends on what you want to do with it and what car it's going on. The ECU itself can be (relatively) cheap - up to a few hundred or so.

I've got an Emerald (very, very good) K6 on mine but I'm running injection with Jenveys on an old car so the conversion cost was high - if I add everything up it was probably about £3k

[bababoom]

It,l be going on a old car Mgb but a modern engine fitted, if it's going to cost a couple of grand just for the ecu then it's going to end the project before it's even started.

The ecu itself is cheap, it's everything else that bumps up the price. I've got a emerald k6 on the merc, best thing I ever did.

We need details of the engine, and what mods have been done to it.

[bababoom]

At the moment it's going to be a jag 3.0 v6 out of a 2000 onwards car, il probably be buying the whole car.
The engine will be all standard.

[retrowrongun]

There are quite a few basic standalone ecu,s some have more features than others hence the vast price range , starting from around £2oo-300 upwards to £5-6k

You want to look at the likes of mega jolt , gotech , emerald , weber alpha
First off you need to really have a motor in mind for your project as for eg some systems won't run 12 cylinders for example so may be out of the question for your project !

Would also look at mapping the said ecu as most tuners will charge 3-400 for a good rolling road/mapping session and to be honest depending on engine and tuner and how familiar with the software he is can take 3 or 4 sessions to get right
This is made easier if you know someone who can map it for you for few beers

My advice would be get the project rolling and once decided on an engine look about and select a management that works and is easy to map with software provided , some are a nightmare to use even for an experienced mapper

In the meantime read up about ecus out there as will help with understanding what you need from It

Here's emerald site for starters

Thanks for the link, all I seem to have been doing the past week is reading up on different things regarding this engine swap.

[bmw2101]

i don't know where abouts you are but wayne scofield aka chipwizzard will be able to take the chip out of your standard brain, convert it to a removable one if it is not already, map your car, and burn you a bespoke chip for around £350.

Wayne also probably is the best in the country atm too, he is in warrington

[bababoom]

So if I got the engine and loom in there car give him the car and ecu he,d be able to get it up and running?
The other thing I'm stuck on is most modern cars/engines these days are fly by wire, how do people get around that?
Al of a sudden a carb fed v8 seem a lot less work lol.

[froggy]

I've got a complete manual s type at work and I'm pretty sure it's not can bus networked so you should be able to use the jag Ecu with the transponder and key . You'll need to run with the cats in the exhaust and the four lambda,s to keep it happy but whatever it takes to make the oe system work will be a lot cheaper than going standalone

[bmw2101]

speak to wayne, he can do lots of good things with the standard ecu.I am sure he will be able to get rid of the imobiliser too.

I think with the fly by wire also, you just put a bracket on the throttle body to take a cable and bin off the fly by wire.




My car is going to wayne in the next month or so.

[bababoom]

Does he have a web address? Be handy if he could do away with the cats via the ecu to.

[wheelspinner]

Definitely set on a jag engine?i know someone who could probably fit you up with a mazda v6 on triumph bike carbs which will run off a megasquirt and get a reliable 200hp she has dropped a couple in mx5's and her Fury. crapengineering.weebly.com
Nick Phelps (Cheltenham Porsche Specialist) runs a jag v6 in his lotus might be worth dropping him a mail [e-mail] I think it runs an Omex.

[Adey]

I'm using an omex 600 on my mk1 r5 turbo. the guys down there are really helpful, you could probably set it to use all the stock sensors too. If you can get it to use the stock sensors and use a semi assembled loom you will save money. Id also stick with cable throttle body too if you can, and ecu to run FBW throttles are expensive and then need lots more inputs and sensors, thats where the money goes

[bababoom]

Not 100% set on a jag engine but at the moment they seem best value for money, you can get a whole car for as little as £500 with a good engine and there 240bhp in standard form.
So I think pound for pound it's going to be had to beat it.

[mdh]

If you're not familiar with ecu's and Efi, the Megasquirt manual is a good place to learn....

Merc w126 s class. 300hp alloy v8 for £500 and it will run on 3 wires.

[bababoom]

Do they come with the option of a manual box and price wise under say £700?

[carat 3.6]

You get the complete car for around 500, the rest of the budget goes on adapting a bmw gearbox to fit.
