Octane is the main thing there. On 93 octane should be OK on map2, give it a pull and ensure it feels smooth/runs well. You can always post a log here if you want us to double check it.

Thanks Terry.

Here's a couple logs...

Thanks for the feedback. Got a bit of a longer run. Car feels like its pulling strong, running 93. Feels like I can maybe go for map 2. Thoughts?

For any particular speed or duration?

P.S. if anyone in the DC area knows of any tracks or safe areas to drive it would be appreciated. Doing 90 MPH runs in 35 zones is risky.

Have any RS owners here gotten the Red Alpha Heat Exchanger? Infiniti Motorsports site actually has the "partnered" one with the Infiniti logo on it, similar to my AMS Red Alpha Intakes which I had installed at my dealer.

If I get the heat exchanger I would probably want it installed at the dealer to avoid any complications.

I have, as well as a several other owners in the q50/q60 forum and fb group. It's the same thing, only the printed logo is different. I installed mine myself btw, can't justify paying ~$500 for labor. Been 6 months now and so far so good.

Hey Terry,

I recently upgraded my LPFP with a Walbro 274 and was logging running E30 at higher boost than previously and I had assumed that the new LPFP keeping up fuel pressure/flow would have gotten rid of my AFR spikes at high boost but I'm still seeing a couple.

Would you mind taking a look at the 3 pulls on this log and letting me know if anything seems terribly wrong? There's one spike to 21.8 AFR in the last pull at around 3k RPM but it doesn't coincide with pulled timing or anything.. infact everything else looks perfect - target boost is being hit, ECU is advancing timing just fine etc.

Thanks!

What timestamp are you referring too? AFR is mapped lean during "lean spool mode" within the ECU so that is as expected. We don't have fuel pressure logging active yet on the firmware, and there would be no symptom to a low fuel pressure situation other than seeing it low in logs, or a low fuel pressure fault. Low fuel pressure would not effect AFR generally.

Thanks for the quick reply! I was looking at the spike around 1037s.

What about if the stock pump was crapping out and not delivering enough fuel, wouldn't that result in an AFR spike? Sorry if that's a dumb question.

I dropped it into 3rd with the paddles and then WOT... Hopefully these give you an idea. Map 2.

Looks like I hit 21.2 psi of boost at peak.

It varies but it'll definitely get heat-soaked eventually. Its advantage is it takes longer time to heat up and shorter time to cool down. As an example, on a 90+ temp with 45mins crawling traffic, IAT temps reached ~135F and then less than 5 mins to bring it down to ~100F on straightaways. Stock HE took almost twice that time to cool down during my testing. YMMV

Seems normal to me. Trims are high due to E30 mix and higher map, but AFR is in check. Leak spool mode will be in the stoich range then richens from there. Boost seems normal for the map.

If it's not running smoothly though I'd drop down to map2.

An LPFP does not change your AFRs, unless you were having low side pump issues keeping up with the HPFP. It usually only does this at the beginning of 4th gear with low rpm, high load when boosting higher (20+psi).

At the time I noticed those issues I was actually running higher boost, around 20 psi lol. I don't push that high anymore but that's what I was getting at.

Still don't understand why my AFR shoots to 21+ while ECU is in lean spool mode though... Terry mentioned above it's supposed to be near stoich but also said my logs look fine.

Hey Terry did you get a chance to look at my logs above?

Is there a good tutorial or YouTube video on what we should be looking for in reviewing them on our own? It would be nice if BMS could create a YT video if there isnt one already. Thanks.

Hey Boxy, what is the AFR supposed to be at? Just curious for reviewing my own logs.

Seems OK to me, but more octane would probably help there. Don't have a VR30 specific how to read logs thread. But at some point will work on that!

Cool. What do you look at to determine that more octane would help? Do any off the shelf octane boosters do any good? Trying to learn here so I dont have to bother you every time!

Anything less than $10 a bottle is typically useless. Stick to ones that use MMT - like NOS Racing Formula. An E30 blend of (1:4) 93 and E85 also works well!
