Fuel is momentarily cut off during the shift, so AFR isn't going to be accurate at shift points.

Logs look good to me though. What's the fuel mix?

Fuel is E30 for all logs. I added the DA and temp on the log title.

2018 C43, E30 fuel, 2280DA, 88F. Throttle closure is MUCH better now. MPH is off a slightly, but also improved.

I will post more map 7 logs when time allows.

Log looks clean! I think to move things forward we're going to need to push boost up. To do that we may need to work out an add on wire or two for the JB4 to add to the wastegate duty cycle. I'll have to get a C43 to swing by the office so I can poke around a bit.

Terry, getting my schedule A service next Tuesday then will install my JB4 and will provide additional logs for review. Thank you for helping take this platform to the next level.

Hey Terry,

Thought I'd chime in here as well as I was able to obtain some logs after doing some runs on the new firmware.

Just a little info on what I've got:
- C450
- Outside Temp was 17.9 Degrees Celsius (64F)
- DA was 942Ft
- Fuel being run was 94 Octane

Map 2 definitely feels noticeably stronger after the new update - if there's any additional combos you want me to try let me know. I'm hoping to be able to hit a dragstrip close to me this thursday and obtain even more logs.

Here are my logs - Happy to answer any additional questions:

I know a guy in the LA area that can drop his C43 off for a few hours for the wastegate testing. Want his contact info?

Hi Terry,

Map2 logs.

80F
83% humidity
93 Pump gas
K&N & catl3ss D0vvnpip3

Is the boost kind of low for Map2? Fuel trim and timing looks OK...

Does the boost increase after the engine heats up more? Made these runs 5mins after morning start up. Though temp is warm here...

Update to the newer firmware and relog map2.

Terry! help us 450 owners hit the times that the 43s are lol..

So I went to the dragstrip on thursday with the following config:

C450
DA was 1463ft
MS109 Race Fuel was used
Outside Temp was around 19 degrees celsius

it seems as though the difference between the transmissions (9 Speed vs 7 Speed) is the reason why C43s are able to cut into the 11s and I'm stuck in low 12s (12.3 was the best I could get @ 115 mph on Map 7 - one of the C43s got 11.7).

I'm of the opinion that they're more geared to run in the higher RPM range with the 2 extra gears and thus get more access to boost.. I'm lucky to see 20 PSI.. car just doesn't wanna do any higher than that and the only time I saw 20 PSI was at the track when I ran MS109... otherwise I usually never see anything higher than 19

Anyways I'll include my logs here for your review. Let me know if I need to be doing something differently.

Hi Terry,

Uploaded the Test4 FW. Attached are logs for Map1 & Map2. Boost seems right on compare to the previous Map2. How does the rest of the data look? If all good, any way I can tweak it more with just 93 pump gas? (93 is all I can get here.)

So there is only 1 psi difference now between Map1 & 2?

Tuning looks good. For kicks on the race gas you could try a map6 with a +8psi target just to see if times continue to improve. Ultimately though I think we'll need to get wastegate control going to push boost higher.

Yes roughly a 1psi difference between map1 and map2 now.

Timing and boost look good, as do fuel trims, but we need to get AFR working on these! Anyone with a C43 that can't log AFR in our area we'd love for you to swing by for an hour.

Sounds good... based on the logs I provided is there any particular rpm range that you would recommend I request 8psi?

Let me know if there is any way I can help with wastegate control... unfortunately I canít be there physically but I am more than happy to help beta test anything out and provide logs and data. Really wanna see this platform and jb4 do great things together!

We'd need a local car in here to play with. As a test you could just ramp boost up to 8psi using map6 and evaluate.

Default How does this log look? - Yesterday, 05:36 PM

Terry, here is a log I did and I’m wondering what you think. The trims look high and the afr looks a bit high as well but I wanted your opinion. I’m just trying things out to see what can be done.

DA: 1,345
Temp: 89F

Would need to see higher RPM to see if fueling sorts itself out, but we'll have to get the JB4 fuel pressure connector installed likely for this heavy E85 mix on map7 levels. Which on older harnesses (with purple plug on them) requires relocating a wire in the DB25.
