Hi,

Familiarising myself with R4 software off-line i.e. not connected to car.

Using Underdog Guide, I have followed set-up steps to:
* Create New Customer
* System Settings->Display Mode->Vacuum/Pressure
* System Settings->Application->Prog. Signal Calibrator

But I have checked Output Settings which are not supposed to be changed (unless E Model FTC which doesn't apply) and the image below displays the default settings.

My question is twofold
a) Are these default output settings overwritten when I upload the map from the SplitSec box
b) Do I need to change any values - the URG implies not.

Oh and BTW, Ive looked at the attached WORD file to the post by teh215 on 5/11/05 which states:
"Namely, you must change the System Settings display mode to "Vacuum/Pressure" and you MUST change the Output settings so that the auxiliary fuel pump will come on. To do this, set the Over RPM to something like 2000 rpms and the Over PSI to 1psi."

So I'm confused as to why URG doesn't mention this?

 

You are correct in setting the output mode to 2000 rpm and 1 psi. You may also want to change the output mode b to over rpm and psi, thats what ive done. I find it takes a bit of time to really learn the r4 software, and if you dont use it very often you tend to forget things. (like how to read the fuel and timing map)

 

OK thanks for that helpful info.

I am however surprised that the Underdog guide which otherwise seems an excellent document misses this crucial step out.

I am further surprised that obviously you can download the 2000rpm/1psi values to the SplitSec box during a 'write' but these are NOT uploaded back when you do a 'read'.

What I was expecting was that the first time you do a 'read' the values whatever they are (lets assumed 2000rpm/1psi ) would be uploaded into the appropriate fields so that I could see what the default values in the SplitSec were.

 

Your PWM mode should be set at....Peasure 0 to 30 psi / 5vdc FS

 

Thanks

I got off my a** and did some digging and came up with this thread, which has a few contradictions versus 'system setting->application mode' (see backagain's map post) but I think gets me going in right direction

- I'm gonna set to Programmable Signal Calib. BTW

Not exactly on thread ..... but when I get my Zt-2 hooked up, what side is best for the O2 sensor i.e. is one bank more prone to run lean than the other?

 

Plus you better reset your over RPM and over Preasure...or your aux. fuel pump will not come on untill you get to 7psi or 6000rpm . 3000rpm and 1psi is safe
