Re: Injection End Angle

I see 0deg as the cylinder firing, and as it is called...TDC. That was the only graph I could find, so ignore bottom numbers hence why I mentioned the 380-420 as you can see this would be IVC. 0deg is the start of a cycle, 720 ( or maybe 719 ) being the end of the cycle. So scale at the bottom of t...

Re: Injection End Angle

Thanks stevieturbo. Can you answer the question on whether 0° on Syvecs = the start of the Induction stroke or the power stroke, they are 360° apart? Perhaps I could find the answer in my SCal file if I knew where to look. The example you show has the power stroke at 0° which is not what I expected.

Re: Injection End Angle

Have searched long and hard on the forum, internet and Manuals for an answer on how Syvecs is set-up with respect to injection angle. For me the 4-stroke cycle is :- Induction, Compression, Power, Exhaust, so based on that if you wanted to inject through an open valve, an injector closing time betwe...

Re: Using Maths channel to Tune for Volumetric efficiency

Thanks RICE RACING, Can see how you have applied VE logic to your tuning, hadn't really considered whether I could use VE to define the fuel table. Agree with your comments on the need for fuel pressure to be accounted for, I have relfp1 accounted for in the turbo air flow calculations, the formula ...

Using Maths channel to Tune for Volumetric efficiency

Am still at the start of my Syvecs tuning journey, working out how to get to grips with how to best tune my engine. Due to the potentially unusual temperatures created in and around the engine bay, I am not a huge fan of Dyno tuning although have to agree the Dyno is a safer method, so wanted to use...

Re: GPS Sensors

Pat,

Would like to the GPS speed output from the R35 GTR canbus.

Do you know if this is available from within the Syvecs parameters in the logging configuration?

Also been looking for the ambient air temperature, possibly also available on the canbus, but can't seem to find that.

Thanks

Re: Using Maths channel to calculate turbo airflow

RICE RACING and stevieturbo,

Since I am new to Syvecs, I will bow to your greater experience and continue to play about with SCal to expand my knowledge.

As said earlier, I have no concerns over getting to grips with the system, just how steep the learning curve is.

Thanks for your input.

Hugh

Re: Using Maths channel to calculate turbo airflow

Referring to your last sentence, are you looking for a list of what each abbreviation is? After looking at the partial list on the site for download (or here on the forum), you can pretty much figure out what all the rest are. That said, there are one or two items that remain blank to me as well, t...

Re: Using Maths channel to calculate turbo airflow

Hi Paul, I am an enthusiastic amateur, not a professional motorsport engineer and assumed that since I was able to wire and tune a Motec MXXX series ECU from scratch using the manual, plus having other ECU configuring and mapping experience that I would not have to worry about understanding the logi...
