Standard NA6 injector size

[StanTheMan]

just trying to get my head around Volumetric tuning.

whats the standard size injector for a NA6.

[Uncle Arthur]

205 I believe

[StanTheMan]

sweet I'll try that.

can anyone explain to me what volumetric tuning is & how it works?

be kind & use simple engrish please.

The VE fuel map basically calibrates the engines VE to a specific AFR/Lamda.

For instance if you were to set a target AFR of 15:1 for all loads and rpm (target AFR tab in wari/seukukuskuku), then tune the VE map so that every single load point ran 15:1 AFR, your VE map would be calibrated/tuned. This then allows you to change your target AFR table which in turn alters the AFR the engine will see, without adjusting anything else like the VE map.

It is very handy, you can change AFR's easily, without a retune. If you were to do the same thing with a ms fuel map, you would have to adjust each load point individually and check with a wideband.

Also remember that dead time/lag/latency is quite important. This gets a lot of people with PFC because they don't know what they are doing and adjust the latency to get the car to idle but it throws out the rest of the map.

Any physical change to the motor (cams, timing changes, intake, turbo) will affect VE, but it also affect a ms table so its no problem.

I think this is a basic of VE

I have only ever dealt with VE and know how it works ( I cant explain it )
When Andy from Adaptronic came buy and said Hello. I said GET RID OF THE MS Tuning
To this he Said The next upgrade will be VE I havn't look back

in the Adaptronic program once upgraded you can convert MS tuning to VE tuning

I do have issues with idle


dead time injector correction........

no idea where to start there. its been adjusted but no idea if its been adjusted correctly.

in my logs today the voltage only varied between 13.8 & 14.2.

idle can be right on target & then will start hunting & then become really stable again.
mmmm
