Yup that's it Haggi Nick what are your ideas, I would like to hear them

[oakmere]

John said Klassen was doing some official development work for Opel now which could lead to more info regarding the z22se ECU. Hope you get it up and running soon.

No higher I am putting the smaller pulley on as I have a couple of ideas about heat build up

And so the 400 battle begins.

my money is on Joe

More info on the Z22SE ecu is off course excellent, but the Ecu / operating system itself is not really suited for boost use, as the fuelling is mainly based on TB position vs. rpms. But still ok for the fixed SC boost, although the fuelling table resolution is limited...

[NickB787]

Yea I know but to be truthful at this moment in time I am happy just to get the car back and running I will take a back seat now in development work for a while as I feel I have spent enough on the car for now.

Was the system running rich during the 366 dyno sesion Nick?

[NickB787]

I spoke to Jon from abroad and am still there now so didn't had a long conversation therefore don't know

[smiley]

Would be interesting, as the stage 2/3 maps run relatively rich, and the stock z22se ecu has 8 bits fuel tables, where the tubby (and lsj) ecu has 16 bits.

well been flat out today got the intake spacer on, manifold all fixed tight, ordered a map sensor from cms along with a water temp sensor, then found my old water temp sensor along with the map sensor at the bottom of a box, so will clean the up for spares can't fit the harrop till the map sensor is in place, that the first job when it arrives to check the belt length.

[rik]

whats your plan now?

[NickB787]

Run the car with the oem ecu and then look at the either the dta or lsj/hp tuners but I am just going to run the car I have not driven it properly for 2 years. I have had enough of R&D

[NickB787]

Well I am here again in the waiting room It was lovely driving a car which drove like an s/c again. waiting to go on the dyno.

[techieboy]

So using Mike's map was already an improvement on the maps that went before (both Z22SE and Z20LET ecu's)? That's encouraging.

[siztenboots]

just avoid speaking to Mark, otherwise abandon all hope

[rob999]

Letting the guessing game begin. I'll go for 366bhp.

[siztenboots]

333bhp

[NickB787]

Not bad Rob.. First run 362/292 very rich also still climbing at 7200 so going to increase 7500

[siztenboots]

has final decision been made on the pulley and expected rev / power band

[Exmantaa]

Not bad Rob..

First run 362/292 very rich also still climbing at 7200 so going to increase 7500

The Harrop shines withs revs, so go for 7500.
Do they also check the part throttle mapping??

[NickB787]

Yep part throttle mapping being done as I type my old coil pack looks like it died new on and running better. 2.9 pulley is on not going to make 375 which is what I was after probably because the engine has done over45000 since I put the harrop on so a bit down shame really.
