Installed parts and DSMlink initial setup done. Now what?

[nwbDSM]

I finally got around installing Denso 720cc injectors, FMIC, and AFPR. Two most time consuming tasks were (1) finding place to install AFPR and (2) Trimming and fitting the bumper

After the installation, I set TPSVolt to 63 v. and ISCPosition to around 30. I then followed the initial setup and idle tuning demos on ECMLink website. By the way, I'm currently running DSMLink v 2.5.

Everything went well, I set the global to -37.5%. At idle, the rpm was set to 750, AirFlowPerRev was between 0.23 - 0.27, and CombineFT was around 1-3 % according to the video demos. I also saw that I no longer have a knock issue (at high rpm) and max out injectors.

I have four questions though.

1. I adjusted base pressure to 42.6. I did both (1) when the car is off, using DSMLink to turn on fuel pump and (2) at idle, unhooking a vacuum line and plugging it. I checked it with the car off, turning the pump on with DSMLink, the base pressure is correct at 42.6. But when the car is idling, fuel pressure gauge read about 5 psi lower than what it was set. Is it common or did I do something wrong?

2. When watching the demo, I saw that, in the video, air fuel ration is aroudn 14.5:1. However, mine AFRatioEst showed ~17:1. Why mine was way up that high? How can I lower this number to be right around 14:1 like in the video? (See attachment for my log)

3. At this point, is it okay to drive a car? Would it hurt the engine or would it be okay as long as I'm not doing WOT?

4. What else I should do next as far as the tuning goes? Any advice on how to do street tune? I know that I probably need to get it tuned by professional. But I am planning to get ECMLink V.3 and Wideband first, before I get a dyno tune.

Any advice will be really appreciated.

Thank you.

It's fine to drive as is. Don't start tuning for WOT until you get a wideband and have it logging in link.

Thank you for a response

So, you mean, if I were to do WOT tuning even street tune, I need to have wideband installed first right?

Ok, if not WOT tuning, is there anything else that I should do or keep an eye on my log (like Knock) to get everything dialed in correctly for daily driving.

you need a wideband.
but you also need to get your airfloperrev upto .25 watch the dsmlink demo videos they will show you how to do this.

watch them as many times as you need to. it took me awhile but its seems simple to do now.

get a wideband. this cannot be stressed enough.

Any idea why my log showed AFRatio 17:1. Is this because I don't have wideband?

Thank you for a comment.

Yes you're not mistaken, fuel pressure shoud be 42.6psi but when you connect the vacumm line to the AFPR the pressure will drop due to the motor being in vacumm and not in boost...

The AFRatio is just an estimate...DO NOT use that to try and tune off of...
You must have a wideband to do a safe tune...

You should be able to safely do a low end street tune. Just vary the throttle, be at different rpms, don't be afraid of a little boost (factory), and just keep the rpm'below 5500-6000...

Watch from 6:30 on about what/how to capture values and change the thresehold to keep the car in closed loop longer...That will give you more points of range for the car to calculate from...then when your done don't forget to reset the thresholds back to the factory values...(Personally I keep the throttle position about 50% from 5000rpms on...)

Edit: Looking through your prefferences I would personally change a few items if I were you...
Under the dash tab...

Knock CEL......I would put to 2....I personally hate knock and I always would shoot for 0.....you have it set at 5 now
Coolant Temp CEL....I would put it no hotter than 220 at the max......you have it set at 232 now
