Well, I like a little boost my GSi nova, as I can do to modify the two ECU?
thx:d
remove them and buy a mappable one, like omex, dta, megasquirt, the standard ones are very difficult to modify successfully.

But as it is connected with the electric car loom? How do I get the ECU's of gr. a clubman spec?
the gr.a spec ecu's were the bosch type, and the engine was high compression, with other internal modifications, and produced about 150hp. the bosch ecu on a nova is so basic that they changed resistors in the circuit to make it fuel better, and also to change the rev limit.
the big problem is that they stopped doing them in about 1993. and they would only be any good on a group a engine. a road car engine that is modified differently will need a different ecu.

On the nova GSi ECU's can not put any chips?
no. they don't have a 'chip' the bosch ones are not mapped, they are a circuit that measures the engine speed, throttle position, airflow, engine temp etc, and create an output. they really are that basic. i have done a lot of readiing into them to try to work out how the can be modded, and i am saving for a mappable ecu.

Tell me more about mappable ECU´s, please. How do I get my standard E16SE work a little better?

have a quick look here

The later GSi engines (C16SE) run a multec ECU (delphi/siemens or similar I forget which). They do have removable chips:

Ummmm, good information. But the siemens ECU work well with the Bosch ignition ECU?
you would need to swap all the electronics over to suit the c16se engine, including a lambda sensor in the exhaust. this is why it would be better to buy an aftermarket one.

Yep I agree, though if he could maybe strip a scrappy car it would make sense. Aftermarket is definately sensible, though I might be biased :)

:wtf:
I think it's best for my economics test with the DTA ECU fast, and if I change my ignition ECU with a coilpack and tuned megajolt?
if you buy a decent coilpack, then the dta ecu should be able to control it.

What you recommend I use? besides, I have to connect the wiring of the car?
i think you should try to get one in spain. these things need mapping, so a local rolling road would be useful. as for the wiring, they are quite simple, but you will need to modify the car's wiring loom to connect to the new ecu.
i bought a spare wiring loom ready for when i can afford to do mine.

Sure, but here the novas modification are very poor. Only in Uk i found good parts to tune my nova.
Therefore, I seek information in this forum. You you have the best tune nova´s , plus also I haven´t a dyno near my house. I'll have to adjust the ECU map on the highway and road.
Too many problems for a car so small.lol
a big problem then. email dta, weber, omex and any others you can find & see if they have a dealer near you

The real problem is not getting the parts, but it is like moving into my engine.lol
For a coil pack you can use any of the Vauxhall 4 cylinder ones (from C20XE and the later Vectra's etc) However I'd recommend using the amplified coilpack from Corsa A/Corsa B C14SE, C16SE engines. Takes the load off the ECU coil drivers makes it run a lot cooler.
Find a decent rolling road tuner near you and speak to them about different aftermarket ECUs, the DTA software is easy for any one who knows what they are doing. You *will* need to use a rolling road at some point so you may as well speak to them at the outset.

Thanks guys, i tried to find a DTA dealer o another Re-mapped ECU dealer. I will tell all my progress:thumb:
www.mefmotorsport.com
Email Martin and tell him i gave you his contact. He is a main dealer for DTA also the people who run DTA attend my motorclub and are close Friends.
He will probably be able to supply you one cheaper than going to DTA yourself. He's clued up and will ship abroad.
Cheers
Dayle.
Did that martin have a nova on here years ago? A 1.6 turbo 8 valve?
No mate, he has had many a rally car though but never a Nova.
Cosworth powered mk3 Fiesta Rwd
Escort Cosworth Rwd
Rover 200 XE powered rwd with subaru running gear
Now runs a C2R2 Max and is currently building a M3 Powered 1 series BMW rally car.
Top bloke and knows his stuff. Very handy person to know when it comes to fabricating stuff.

Well I have already made contact with him and impatiently waiting for your response.:d
Thanks for your patience with me Dayle, and the other guys too.:thumb:
You would be best suited with a DTA S40 he also makes looms too and can supply you with coil packs sensors etc if need be. I'm sure he will have details of someone close to you who could map a DTA too.
I know of MEF from the DTA forum, seems a sound guy :thumb:
