14:1 here I come! Is it sophisticated enough to handle a high compression NA?

Doubt it if you're planning ITB's unless you really fcuk about with the throttle position sensors or jury rig something to be driven off the motor in the throttle body. Remember, it's all done to retain the existing drive by wire setup.

Good point. Alpha unit is a PITA as you need to bring it to a certified tooner!

I'm not convinced but i dont think its worth the argument But if any of you who are going to the national would like ago of my car to see what you think you are welcome to swap cars for a little run

Only an argument in the debating sense. As it stands, map wise, you probably haven't got anything more or less than a run of the mill stage 2 custom map from Courtenay's for your car. The key thing is, you've now got room to grow without any need to go back to them. If you ever want to go stage 3 and/or fit bigger injectors or different exhausts or go Harrop, that's when it'll really pay you back. Sure you can go through 200 free (assuming you don't assign any value to your time) mapping sessions on what you've got now and add/remove fractions of a degree of ignition if you want but, it'll really just be for the sake of it and make only minute differences to where you're currently at and probably be unnoticeable as far as driving is concerned (any placebo effects aside). Don't for a moment think I'm a Courtenay's fanboy. Even if my drive is only 100 miles, it still p!sses me off deeply. Despite what Smiley likes to think, I'm not trying to say Courtenay's are better and that OBDTuner is some form of black magic and am just trying to bring some reasoning to it. OBDTuner will suit some people/circumstances better, just as to some people it wont make a blind bit of difference. Like I've said numerous times, if I was starting out again from scratch, I'd have been beating a path to Peter's front door to get the software (the money I spent on NA mapping at TMS and Superchips would have more than covered the cost and this would certainly have delivered better results back then, if not now). As it is, I've no plans to do anything further with this setup or engine so the ability to tweak the map and alter configuration is of little tangible benefit to me (though it doesn't mean I don't think it's the dog's dangly bits). I think.

[CHILL Gone DUTCH]

I've already upgraded the injectors from the black ones to the blues as they were running at 99.9% duty cycle, The software told me this Does that mean in I credit now lol

[techieboy]

Probably not. Courtenay's would have told you that, or got the pliers out on the FPR. Seriously though, going on what I've paid over the years, you'd probably break even at three distinct Courtenay remaps (e.g. three visits). I saw you mention your VXR injectors are at 85% duty cycle. Fcuk knows what mine are at given I'm running a 300bhp Stage 3.

There is software available that can tell you that.

Ask courtenays Lol

[smiley]

Our angry admin is right though.

 

If you're happy with your CS mapping, as you're not a fidler and more of a set and forget type, this is a waste of money.

Only buy this if you know you're gonna hang on to your vx for a while, and tinker lots with it.

 

[CHILL Gone DUTCH]

I see this as a conversation not a argument Fors and against

[NickB787]

What I like about this although there is some considerable outlay in £££ from here on I should be able to look after the car on my own (I hope).

 

For me I have had enough of ECU's z22se, z20let DTA and any others you care to mention.  I just want to mess about a bit with my car, change a few things as time goes on and learn. I also hope when the new intake manifold is produced it will be a simple game to map that also

[smiley]

What's not fully clear from the harroped guys jumping on the obdtuner bandwagon now, what is the cms mapping status for it?

Is it possible (with limitations?), or is it practically mandatory to use obdtuner for those?

I think lee has had a result from CMS don't know if he is happy with the result or not

[Exmantaa]

 

I believe you can do this with the HP-Tuners / LSJ ECU route as the LSJ engine comes as standard with a boost control solenoid (attached to the port we leave open on the bypass actuator I think - Exmantaa will know), so it could be retrofitted, but then I guess you have no control over it with the Z22SE ECU...
 
Some info at the bottom of this page:
 
http://www.redlinefo...solenoid-2.html

Ahh, didn't know the LSJ had one of those as standard. Might keep my eye open for one to go on this B207.

 

 

 

Yeah, the original US LSJ ecu has quite some torque management build-in. Even a gear specific boost control. (mostly switched off in my car ) Very simple to retrofit on any supercharged Z22SE, as the necessary connection is on every M62 bypass actuator:

Simply connect the lower (now open) actuator connection to the manifold/FPR pressure line, the build boost pressure will then open the bypass, limiting boost.

Put an (LSJ) solenoid in this line with some PWM signal and you can regulate SC boost pressure.

Good to read that the OBD software is now working well for you guys. If this was ready a few years earlier I would have used it too, but now still very happy with my LSJ ecu conversion.

 

 

And a question for the knowing; how is the Z22SE's "low res" 6-1 crank trigger with a revvy engine compared to a high resolution 58-2 trigger? (ignition timing errors etc.)

[davemate]

i emailed peter about a question about the widebands and asked what would be the best way to go about a lower power map... he replies with a throttle position map, apparently the first 10 cells are used for idle so cant mess with those, but here is a low power map that will mean i am much more happy with somone else driving the car (for example borrowing it for some driver training prior to coming on a track day) or if i just want a lazier drive.

[Scuffers]

never got that, why do people need multi-maps?   variable boost I can understand, but why several maps?

Some people might not be going 100% all the time and might want to drive more Eco Like redbull F1 teams do somtimes

  

Or have a detuned version for when it's raining so that you don't stack it.

that's an argument for variable boost control, not for multi maps.

I am happy with my CMS Harrop Map but will be going Obladi Oblada after the race season finishes.

Obladi Oblada

Can't get that song out of my head now.
