dsmlink injector adjustment

[Kibby]

I was reading the table as a guide and noticed it says its based on stock fuel pressure 1g AND 2g. Now I believe the 2g has more pressure. My question is does the dsmlink when switched from a 1g to the 2g maf compensate for the difference or does it still run fuel maps based on the 1g stock fpr? Maybe im over analyzing it but aside from tuning wouldnt the car run a little leaner with less fp on the base map?

Changing base maf type will not change your fuel settings. They are separate within Link.

I know. What I asked is does the dsmlinks fuel map still run off the 1g fp or does it run on the 2g fp when switched to the 2g maf. I'd assume it would require less ID with a slightly higher pressure but im not sure.

This may be a question better asked on the Link forums. But I would ASSume that the only thing changed is the airflow difference between mafs.

Either way, it's pretty close. If you make such a change you can just readjust fairly easily.

Is does? Wop answered your question exactly. Not sure what you are confused about.

Yea, your English needs work, but I think your asking if you switch the tab for a 2g maf, does link still use the 1g fuel pressure? If that's what your saying, then no. The airflow and fuel adjustments are always separate. This is left to the tuner to make the proper adjustments.

I dont need any work on my english!!! Its pretty simple. You have xxxcc injectors running the 1g fpr or the 2g fpr which is higher. The end result is if i was running the 2g fpr more fuel would be dumped if a 2g fpr is used on a 1g car 1g maf setting. Im going on the rule that increasing fp you get more out of an injector. Though the difference between the 1 and 2g is small I was wondering that when the injector gets to such a large size that the ecu will treat the injector as a 2g fpr setting and not a 1g. Therfore less ID would be used. So I guessthe question in better "english" would be should the 2g fpr be used when usng the 2g maf setting on the dsmlink? Like running 3 bar vs 4 bar fp

Sure, you can use the 2g FPR, but you still have to do the correct injector/fuel pressure calculation under the fuel tab.

What size injectors are you using? You shouldn't be using a 1g or a 2g FPR IMO, you should be using an AFPR so you can set and monitor your pressure at the rail.

Rc550's.

 

[GSTwithPSI]

Did you upgrade the fuel pump? And, what regulator are you running right now?

 

[Kibby]

Walbro 255hp. stock 1g regulator. Also have not done the fuel pump rewire yet.

 

[diambo4life]

Just leave the 1G fp regulator in place.

Not if you wanna deal with fuel pressure overrun. The 2g is even worse for overrun. I hate tuning cars with stock FPRs. You can do it, but it's a PITA.
