The main reason is fuelling the Courtney map is ok and is proven works but with this map it should be much better on fuelling actually the ecu will be working rather than guessing

[slindborg]

Now, what would ice the cake is having a can port open for those who want a sensible logger and vbox thing solution. I imagine the code is as mature as most aftermarket code in that (no offence) its p*ss simple and the key is calibration it right.... Get the cal wrong and bang.

I'm going to wait until I've done my mods next year.

Don't fancy using a base map for a NA
To map a SC
So better to wait unless someone can tell why it would be ok

From the thread it'd be fine to run it on NA and when you SC it the ECU would need to relearn as Oakmere describes in his first post. You wouldn't need to repurchase the software.
EDIT - just reread and £75 to upgrade to SC

Although until you make any mods a std engine would only really benefit from the raised RPM.

One guy alexb said he had mods put on ECU before he went into self learn mode again for 75 euro . It was a SC

I'll bet you could also iron out the emissions flat spot in the power delivery as well and bid farewell to the EGR triggering.

I think that's because he had the first version of the custom firmware, which only supported NA applications. Then paid to get the later version of the firmware once that had SC support added.

Ok sorry didn't fully understand
Bit clearer now but would prefer the mods on first map from Peter

The PDF on this says you can simply turn the egr sensor off.

Yep turn it of and lambda sensor aswel sounds the nuts

true, and there's the change in throttle response


Oakmere, have you played with the throttle settings?

The power graph layout looks great also.

As mentioned in this thread by smiley and exmantaa (the explaining video is mine) i am running my car with obd-tuner since end of last summer. First with a 1bar boost m62 z22se, now with my complete 2.0litre b207 saab engine with cams and a harrop. At the moment i need bigger injectors (vxr @ 4.5bar are way to small) and my iat is way to high. If this is fixed i will improve the base-map on the road and get to hitec rolling road to get the final malling. Don't forget: any tuner on this world with a rolling road is able to map the car for you. He does not need any time with learning how to dance with the z22se ecu. No checksum-problems! He just needs the car and your laptop. The reaction to throttle is much better and cold start is no problem anymore.

To answer a question about the group buy. I don't get the impression this is business for Peter so not the same financial incentive to get cash in. Chill I am sure Peter would mail a map for you if you went SC at a later date. I have not played with the throttle settings yet. There is a sport setting which Peter has set as an option in the settings or you can adjust yourself as required. My main focus now is to do a power run then to start calibrating the full throttle ignition but it is snowing again. Soon as conditions Improve I will get on it.

So OBD-Tuner works with the different Saab crankshaft trigger wheel pattern?

Thats the impression I got, he see's it more as his creation like an artist would IMHO. As opposed to normal business ethos. I guess that comes from being the sole developer of the product for so many years...

No, i am running an external crank trigger wheel solution. You can buy a brand new b207 engine with this wheel and all the other necessary modifications at hitec in germany

[techieboy]

Yeah, I've got a B207R and am converting to the LSJ ecu and HPTuners with Exmantaa's help. It was just surprised if the OBD-Tuner could deal with the 60-2 pattern of the B207/LSJ engine, when the Z22SE is the silly 7-1 pattern.

Or buy a b207e and put the bottom end of a z22se on it. Which gives you best of both worlds and lets you use OEM loom and ecu with this software.

This is the rout I'd like to take.

[Exmantaa]

Someone has a Vx with this software on a harrop already and all good apparently

That should be Ultimate who is running a Harrop and wired up the IAT sensor to the intakemanifold. (Z22SE IAT sensor has identical response as a Bosch TMAP, so a simple rewire.)
Edit; to slow...
Mind you, he measured >75*C temps on the Autobahn with a 75mm pulley fitted and 1,55bar boost pressure... That is a lot!!

And as stated here a few times, the new software gives you the tools to properly map the Z22SE, but it gives no magical power and if done wrong you can blow up your engine...

The OBD calibration process itself seems very similar to road tuning with the HPTuners LSJ ecu: Let the ecu optimise it's fuel trims in cruising and low load in Closed Loop mode (14.7AFR) with the narrowband O2 sensor, then later flash the fuelling map with the learned trim corrections. That should get the mapping close very quickly.
In the higer loads things get tricky, as the ecu normally switches here to Power Enrichment mode (~11.8AFR for boost) and this is out of the narrowband sensor range.
OBD is always in closed loop mode during calibration (correct me if I'm wrong Peter) so the high loads have to be calibrated near the 14.7AFR in short WOT periods with sufficient cooling down .

With the LSJ I prefer to do these higer loads with a Wideband O2 sensor feedback and monitor the fuelling error between the Commanded AFR (say 11.8) and the WB-O2 measured AFR.. (Which should be close to 11.8AFR if the mapping is correct)
Not sure if it's in OBD yet, but it would be possible to log an analog wideband signal through the (redundant) EGR wiring and then adjust WOT fuelling accordingly.

@Cliffie; I would try to get this a.s.a.p on a different Z22SE ecu. It's plug &play with your current wiring/ecu and if iut's not it you could always sell the OBD-ecu here on the forum.

The software looks very well thought out so maybe there are a reason why Peter havent done this allready, but it would be nice if there where an option to use a wideband sensor as main O2 sensor.
