If I pay for this I want an unlocked ecu with software

Because you know how to map a car Nick?

No Mike I don't know how to map a car, wouldn't mind learning something about it though, why I wanted it like this is because I plan to take the car with me to Aussie and I want something which can be accessed for future mapping by someone there not just here in the uk.

Makes sense.

I can only ask the question but I am not pushing this development if there is no market for it.

I can see the pros of the product, but at the same time it is likely to have a lower uptake than that of the webCON throttle body kit... Reason is cost, 90% of modded z22 engines will cope fine enough with the calibration that courtenays can achieve, the other 10% might not want to spend half a supercharger cost just to eek some more go from it.
Maybe ditch the plug and play model and look at a more generic one that you might be able to sell in higher volumes and suit more of the VX modders as it'll be more accessible and have better reasoning for the purchase.

Sage words Stu. I won't pursue it then.

If its a relatively 'easy' task then I cant see an issue atleast getting the option available, but I guess it would come down to business at the end of the day and how much profit (or loss covering) selling maybe 5-10 sets over a few years would get EP/yourself back.
Obviously it would make sense to have either the GEM's or Syvecs etc on your car as its a race car.

I am sure it will be relatively easy but to make it worth while there must be a commercial gain to justify the investment.

I think the real market might be very small.

[Exmantaa]

, but as said the Z22Se's odd crank pattern and lack of a cam sensor could make this less easy, a.k.a. more expensive...

[siztenboots]

I know the trionic stuff doesn't need a cam sensor ( or a knock sensor )

[techieboy]

can't beat the trionic stuff for value for money

Looks like a relatively straightforward swap for a turbo'd car, especially the LET. A whole different kettle of fish when it comes to Z22SE and a supercharged car as far as I could tell (and the people behind it are possibly the most unhelpful people ever). In reality, turbo owners only need apply.

[techieboy]

I would also like to be able to have a few maps I can apply- tune it down to 200 if I wanted and have a map for full power when I want. Drag and drop maps would mean I could let others drive it and enjoy a little of the fun.

Can't see how you're going to achieve that on an SC'd car that doesn't rely on electronic control of the boost. The only way you'll be able to do it, is to either come up with some form of electronic boost control solenoid lash up, or cap the rev limit to 4,000rpm.

You would be able to do a nice MOT specific map and then a fcuk the environment map. But you could do that with any ECU that's "open". You could even do it with the Z22SE ecu, if you could bare the 30 minute download/upload of the maps.

the 94 onwards trionic was also on the NA's

[slindborg]

The boosted software on the T stuff appears very geared toward Turbos and their required controls/protection as opposed to a supercharger, although mostly the S/C is just like running a BIGGER N/A lump in terms of air flow (give or take) so maybe the N/A software would be enough.

[siztenboots]

So the Ecotec LK9 is the Saab turbo'd 2L , with trionic , which is basically the LSJ that everyone is moving over to

[Exmantaa]

I looked into the Trionic stuff too and concluded it was not developed/open enough for an SC. (as in "over my head".) Decided for the LSJ/HPTuners stuff which is much easier for SC's and almost bolt on if you have a Saab head fitted. (if only Joe would fit his O2 sensor we could finally crack on with it...) The Dutch OBD tuner stuff for the 2,2 Speedster seems pretty developed now, but still a bit pricey and only local...

[NickB787]

Come on Joe

[techieboy]

(if only Joe would fit his O2 sensor we could finally crack on with it...)

Looks like my "hold off until winter" project might have been the quicker option, after all. Time to make a start now, I guess.

[smiley]

and only local...

There's a german about to try it on his B207 somewhere this week. Check the german forum.
(all by sending ecu over mail) He seems to be making progress/less scared by forcing people to pop over.)

The SC'd Elise and Exige is no different I take it? It works on there.

Switchable maps would work if you changed pulley sizes each time and you had a map per pulley.

[Exmantaa]

Well, my mate just aquired a Harrop for his Z20NET (= B207) build, so I have to hurry up myself not to fall behind in the power game... Back on topic; I think something that fullfills 90% of the SC wishes for 30% of the price is the preferred option for most here.

The SC has a bypass valve that's not fully used on the normal 2.2 conversions, but on the LSJ it's controlled by the ecu (2nd connection on actuator) to limit boost pressure in certain gears. Easy.

Could this not also be done by limiting the throttle opening? adjusting the fuel etc?

Bummer, thought I had just about all the bits I needed, didn't know it used a boost control solenoid (but that does make more sense of the boost limiting and traction control facilities)

[siztenboots]

or just keep the throttle butterfly opening limited
