just wondered who will be doing your maping rik as the same as joe am very intrested in results of this little venture looking good

me if i can

balls of steel (if you say "if I can")..... I wouldnt relish the idea myself and I'm not exactly unfamiliar with calibrating engines

learning experience, as with all the rest of this stuff

get a 1.6 nova and learn with that better to break cheap sh** should something go awry

it's only a vectra engine

yea but fcuk me do people sell them for a lot (WIN for future plans)

injectors firing in test mode (spark too but can't take a photo of that)

[rik]

anyone know what flow these injectors are (standard z20let ones I believe) I read somewhere 370cc at 3bar is that correct? I think our standard fuel system is slightly higher than 3 bar?

The injectors you have are rated 355cc @ 3.0 bar (3 bar being the industry standard measuring pressure) The Z2.2SE runs at 3.8 bar fuel pressure which upscales the injectors to 399.56cc

starts and idles like a pussy cat
but anything over 1200 rpm it starts to growl like a dog
time for a tidy up then start tuning it

Nice work Rik, glad it's all going so well.

sounds like good progress good luck

The box of tricks that controls the throttle. Software on the chip still being tweaked, and proper PCB being developed.

frustrating weekend trying to find why the engine was running lumpy above idle ( was worried I'd damaged the engine somehow). After messing with all the timing gear and even putting the standard ecu back on to see if it gave me any fault codes, turns out one of the injector pins had come out where it connects to the injector. Put it all back together and running great. I've not taken it for a ride yet, but I'll be putting the clam back on and tidying things up over next few days. Luckily ms has an autotune feature if you have a wideband sensor, so it should be able to get a nice steady map on it after a bit of driving in circles.

how much ignition advance to you plan to use to start with ?

[rik]

got this table from a guy called ecotecfiero on z22se.co.uk who had megasquirted his 2.2 15 10 10 10 20 20 20 20 25 25 25 25 14 8 8 10 19 20 20 20 24 24 24 24 6 6 6 10 19 20 20 20 20 23 23 23 10 6 6 12 19 20 20 20 20 20 20 20 12 12 12 19 20 20 20 20 20 20 20 20 12 12 12 20 20 20 21 20 20 20 20 20 12 12 20 20 20 21 21 20 20 20 20 20 12 12 19 20 21 21 21 21 21 21 21 21 12 19 19 19 20 20 20 20 21 21 21 21 12 20 20 20 20 20 21 21 21 21 21 21 12 20 20 20 20 20 20 20 21 22 24 25 12 13 14 14 18 20 20 20 21 23 24 25 nocked it all down a couple degrees, and then decreased it by a couple progressively by each 10 kpa going over 100kpa (into boost) what does your's look like?

Is that more advance at WOT than at part throttle ?


Mine looks like this

[rik]

hmm not sure which way round that pasted. Not got the file near me at the moment but i'll do a print screen later. what scale/unit's is your top axis? is it throttle position based rather than map based?

[rik]

not mine, but an example ms spark map for a boosted engine

[alanoo]

Nop it is MAP (but N/A)

[rik]

well guys, I bottled it. Two unknowns is too much at once, and I want to get the car running asap, I miss it . I'll continue with the ETC at a later date..
(thanks to rabidh for giving me this idea)


ordered one of these.. 70mm

This way doesn't give enough cable movement to open the new tb fully
So I'm on the hunt for a new pedal with longer travel
does anyone (slindborg) know the price of the pilbeam one or the weber one?

cheers

Pilbeam made me giggle........ wait for it......... £130 +vat and delivery!!!!!!!!!!!! and theirs is the simplest looking setup!

If you are handy with bending metal (or know somewhere that can) then I bet you could get one made for all of £50max Have a look on the pilbeam site for some decent images of the pedal + mount.

That or you could fit a linkage somewhere along the line so the travel you have gives 90deg movement.

I guess I could have a go at making one out of plate
