Emerald ECU tuners?

[rzempel]

Can anyone refer me to someone with experience tuning a Zetec with en Emerald M3DK ECU?

I'm having a heck of a time getting my new powerplant running, and I've just about reached the point that I'd rather just pay someone else to tune it.

I know Gert (slomove) has an Emerald and has done some mapping.

There are Emerald Maps you can download from some link on Blatchat too. Just to give you a starting point.

I have an Emerald ECU that was installed and tuned by JBA Racing in San Diego. They are a bit expensive, but have a dyno and experience with my Zetec in the Caterham.

If you'd like my map, I could send it to you. I'm not sure how close it would be to your setup. I've got Jenveys, headwork, and Kent cams.

Two summers ago(?) we had a mapping session, where Gert's car was included. I would compare Gert's and your engine. If they are close enough, you can probably use his map as a starting point. Ask him nicely and he'll probably mail it to you.

A word of warning: Detonation/heavy knocking under load in a Zetec will shatter its stock sinter cast rods within one second. Be careful when you try out a new map.

One of my better maps is attached (renamed from.fig to .txt to allow upload).

However....this assumes 30-pound Bosch injectors running at 40.5 psi. A minor detail that I am running a 2kOhm resistor parallel to the TPS to achieve better low end resolution. If yourv setup is different you need to modify this.

At the end....without a wideband lambda probe the whole thing become a complete guessing game or I should better say almost impossible unless you copy exactly a certain setup. Going to an experienced dyno operator is surely a good bet but obviously expensive. Given the limited time they can map the most critical areas of your engine but that will still leave a a lot of uncharted territories on the injection map.

I suppose the ignition map has much more latitude and you could use what I got. It is a bit more on the conservative side for reasons Magnus mentioned and Doug knows about ;-)

After several years I am still watching the lambda results once a while and tweak here or there. But that is a bit of idle hobby because given the limited reproducibility on the next drive it will look different again.

I trhink you mean Magnus re: detonation.

Although I knew that too.

I've got a couple of different maps to start from, already--one from Emerald, that I couldn't even start the car, and one from a Birkin that Larry Anderson tuned (that's what I'm working with now). I do have a LC1 wideband sensor, so you'd think that I *should* be able to sort this out, but it's not coming together for me. I also have Eagle rods, so I'm not *as* concerned that detonation will destroy my motor.

I've had some mixed success, so far. At one point, I had the car on the road, but I knew the MAP sensor was bad. I changed the MAP sensor then, ever since, I feel lucky the few times I can coax the car to start and idle--and that isn't reproducible. Grrr.

Thanks, Justin.
