I don't see the point in handing the car to a tuning company when you have this software when the point is you can do it yourself?
I can understand a dyno pull to give a power reading and check AFR but that is it.

Remember for all the SC people the ECU operates in a completely different mode with the OBD tuner. You will have speed density mapping not alpha-n. Speed density uses the map sensor reading to control fuelling. This is very important for boosted applications as the ECU knows when the engine is boosting.
I am assuming CS can't do this so the ECU bases the fuelling on throttle position (alpha-n). If so is fuelling a set estimate + safety margin which is why you get over fuelling?

That's fine and long may you have the choice and ability to DIY it and enjoy doing it. I know how to (or at least used to) drive the car to something approaching it's limits and that's all I want to know. I know fcuk all about calibrating engines, know fcuk all about what is safe, what isn't safe, what strategy to use for this that or the other and frankly don't have enough time to want to learn. I want to be able to go somewhere say here's my car, here's the spec, make sure it idles smoothly with these cams in, make sure it starts and runs properly from cold, make sure it does the same from warm, make sure the fuelling/timing/whatever is spot on in each gear from 1000rpm through to 7800rpm and make sure it's not going to melt the first time I use it on track, thank you very much.

please tell us all where this Inca Tuning Shop of Gold is so we may bath in it's tuning goodness?

Hi I'm here.

but fcuk I'm expensive

This is about the car mapping, not your other services.

I'm not sure it exists. But that's what I want from my ECU (be that standard Delphi, Peter'd Delphi, LSJ or a fcuking McLaren Electronics one) and engine. I don't want to know how to do it. I don't care how it works. I'm not interested. I want it right, to feel vaguely OEM and to never have to think about it again. Until I do something stupid and change something else.

[techieboy]

Interesting.
So who´s going to be the first to buy the kitty, drive it to CS/MMG/Slindy stage 1 on the basemap with above message and see how much it hurts?

Huh?

[smiley]

Huh?

See what it turns out costwise for the finetuning to be done by a tuner, instead of diy..

[slindborg]

He means as in, all that work will take a long time to get right, and time = monies. Mind you from my chats with someone on here, hes having a mare getting the Idle right and all the usual areas to hit arent fixing it completely

[oakmere]

That would be me. Tip for all keep std cams don't fit stupid aftermarket ones. Unfortunately looks like I will have to wait for Peter to fit silly cams to his then I am sure he can improve this further. In defence of the software this area has not been fully developed yet and is 10 times better than it was before. May be I was expecting a bit much to get perfect OEM idle with high lift cams a light weight fly and balance delete?

So what's the fcuking kitty you're talking about buying then?

Like I said, I'm not sure it's possible, whether you spend the next 10 years twatting about with your laptop and OBD lead or pay some tuner £30k in mapping fees. It certainly wasn't possible on the all of the money I paid TMS in mapping for Stage2+ and Stage 2.4 cuntifold. It was almost there on my Stage 2 high-comp SC conversion and it's probably even better on my Stage 3 low-comp SC which is much better than the Stage 2 low-comp SC conversion ever was. But it's not perfect and I don't expect it ever will be. It's also one of the reasons why this engine is coming out and going in the bin as I hate the characteristics of a forged engine and am not prepared to live with it.

I've got no problem paying reasonable money to leverage somebodies expertise and bypass 20 hours of twatting about with settings I don't understand the ramifications of changing.

Do you not have any requirements for what you want from your ecu/map of choice? However unachievable.

Which brand/type did you use?
(a few stage 3 obd´s running in NL, so could be interesting to compare what works, and what not yet)

Given the french couldnt get the 1*2 engines to Idle properly, maybe I'm being a little unfair

There is no reason on earth that idle cant be atleast decent, if not perfect with the lightly silly level the cams the Z22 folks use.

Whats the problem with PCV? I am running a complete b207 engine with obd-tuner and my PCV is not closed... What is wrong with your cars when pcv is not closed?

[smiley]

yes.
Don´t throw eml codes like the German Hitec remap does.
Don´t overfuel like the CS remap does.
Start normally when cold.
Have decent afr from 0 to 7k rpm to save on fuel.
Have decent ignition set so i don´t have knock.

That´s all i want.
So far i´m happy. (though i´m still in the remap proces)

[Mike (Cliffie)]

My idle is fine. Oakmere, is what you are saying that the OBD software is not able to handle high lift cams at this stage and needs further developing?

[smiley]

PCV not closed does not work on CS remap, and not on obd. (Peter also has his closed)
So you´re the first with an open PCV. Hows you´re oil consumption?

[techieboy]

So no different to my requirements (except no EML's here). The only difference is I'm prepared to pay somebody to fine tune it as closely as practicably (and yes there is a cost/benefit decision to be made in there) possible to my requirements instead of wasting hours (or the weeks/months you seem to be spending) trying it myself and potentially damaging something.

[ultimate]

Engine has only 1000km yet from brand new. No consumption seen on the dip stick.

You may have discovered something here
Does the B207 have a pcv opening between cylinder 2 and 3?

[ultimate]

Yes. It is the same like oem - lsj. But there is a small valve in the manifold that stops boost to come through. It is only opened under negative manifold pressure.

[smiley]

(or the weeks/months you seem to be spending).

I´m more of a keyboard warrior then actually driving the thing.
I only spent a few hours on my last update to the blue injectors, so need to spend a few more to get it right. (currently in pieces, waiting for JG´s milltek to arrive)

That blown up engine is really getting into your head huh.
