KMS ecu

[Meatball]

Anyone using it on their chim?, how much did it cost and where did you buy it.

[dogbucket]

it is mentioned in the '+40bhp' thread running in the griff forum by lwt

[Meatball]

Guess not then will try lwt

Hey Ben why don't you get an Emerald ECU much more popular, and lot of places around that can do the tuning. Also would be easy to fit as if you get stuck someone on here would beable to help.

The quest continues for a few more bhp! What exhaust manifolds are you using Ben?

Hi Chris, How much did the ECU cost including set up?

[trackcar]

Loads of KMS ecus out there now .. lwt, pasco, clive f all run kms systems on their cars. I used to have one on my S but changed to emerald because i'm going turbo.

Jon i need more power Im using the standard ones without the pre cats??? The aftermarket ones on here are too much for my pockets.

Had a couple of KMS's in, thought it was very basic.

[trackcar]

To be fair it is basic, but it's still a big step forward from the archaic lucas, and does everything you need in a normally aspirated rover v8 Short of building a megasquirt I'm not sure you can do as much for as little money.

[Meatball]

Talking of money how much are we talking?
Kms with set up and emerald with set up?

If you did the kms install yourself you could be up and running for 800 pounds for all the parts, even less if you bought secondhand coil packs etc.

There was a recent bulk purchase on emeralds on here so you could look in that thread for prices on that ..

the emerald is the better ecu and it has an excellent boost/bleed control for turbo cars which is the reason i have changed.

If youre staying n/a and budget is a primary concern go for the kms.

if you might go boosted in the future or want something a bit further up the evolutionary scale buy the emerald.

One thing I would say though is if youre going to install yourself then the extremely helpful emerald people are easier/quicker to work with than the kms people so if you think you might need some help then emerald score highly on the customer support which might be an important consideration.

Nice one
Ive read that you have your own dyno what sort of gains have you seen going down this route?

[trackcar]

That's something i can't answer for certain as I don't think ive just done a straight ecu exchange .. all the cars have had other mods done at the same time so not a direct back to back comparison. lwt's chim 450 had kms plus a 72mm plenum / elbow etc and gained 30hp on std plenum/lucas. might give you some idea.

Just to help Joo out there, the price for the group buy was about 1K IIRC for all the bits brand new with new temp sensors and a part built loom. Without the group buy last year I think the price was about £1500 for the Emerald, £2300 for the Omex 710 and £3000ish for the DTA system. These may all have changed though I'm fairly sure the Emerald one hasn't. With second hand coil packs, re-using sensors and connecters etc I would have thought that around 1K for the Emerald wasn't far off.

Lots of support for the Emerald both from the company themselves and the folks on here who now run them, with a few TVR garages now starting to get some experience with them for tuning/setup etc

I believe the base unit is £800, plus all the other bits you need. Too much money for not enough IMHO.

[Chimjunkie]

Just a thought, but since quite a few people have done some kind of conversion would it be worth trying the TVR breakers for a 2nd hand unit? What other cars may have one?

Thanks for all the info guys just to throw 1 more in the mix what about megasquirt? how would that compare to the kms?

Unless you have all the time in the world, anything is better than Mega Squirt.
