Okay, I currently have the JB+ on the car at the max setting, but wanted a little more, so I bought the JB4. I have been running only 93 octane, but would like to experiment with e30-50 blends, the car is essentially stock, no intake or ********. When I ordered the JB4, I also ordered the EWG.

Couple questions:

1. Where should I start? Map 3 with the 93 octane, or can I use Map 4 or 5 since I have the EWG? Should 4 and/or 5 only be run on e blends?

2. Is there any specific process for sending in my JB+ for the refund since purchasing the JB4?

Thanks!

I'd log map3 to start with EWG on, default settings, and lets evaluate it. Stick with around an E30 mix to start.

Thanks Terry, that's where I'll start. Tracking shows it arriving on Tuesday, so by Wednesday evening I should have a log to upload.

Terry, I have everything installed, did my first log this morning and it's viewable on my phone, but for some reason I cannot get it to email to me. I have tried both hitting the email block and selecting the log and clicking the blue email at the top, neither seems to do anything. Any tips? Is it even helpful to just upload a photo of the graph?

Nevermind, I got it figured out, uploading file now.

I uploaded the log, let me know how it looks. I haven’t gone to E30 yet, waiting on what you say about this log.

Sorry, I uploaded it to the support and logs page. Titled 2021 Supra A91 Edition First Log

Just put it here. Need to keep all the posts in one spot.

Run looks as expected for pump, there are a few timing corrections so definitely looks like mixing in some E85 will further boost performance when you're ready!

Thanks Terry. I went with an E30 mix today and have two logs. On one of them you’ll see that while I was WOT it shows the pedal at 100% but the “throttle” drops off.

Here are the two logs on E30

[Terry @ BMS]

Throttle is used to regulate boost so when flash target drops throttle closes to redirect boost to target. All normal operation.

Timing looks good. Worth doing a run on map4 also (absolute 20psi map) for comparison.

Awesome, I’ll get one on map 4. Thanks!

Looking forward to that. I tried it in my G20 330i and map 4 seemed slower than map 3. I know cars and engine are different (I have the EWG cable) but curious as to how it works for others.

I'll be trying it out tomorrow and will report back and post up a log from it.

Here is a log from Map 4 on E30. Is there any advantage to going to Map 5 or increasing the ethanol content to E50?

I felt it was slightly less punchy in Map 4 than Map 3.

[Terry @ BMS]

Map4 looks pretty clean. Can do a run on map5 just for comparisons sake. On the E85 mix I'd keep that where it's at.

Thanks Terry. I appreciate the assistance! I'll keep the mix where it is and get a log soon in Map 5 for comparison.

Terry, here’s a log for Map 5 on E30. Thanks!

[Terry @ BMS]

Log seems good to me on map5. As long as it's pulling well you can stick with it!

Thanks Terry, it’s pulling extremely strong on this one!

how much e85 spiguyver?

That is really going to depend on what you're going for and the percentage in your e85. For me when I tested it, the pump was at just shy of 85, so I went with 85 as the percentage. I have heard of people seeing as low as 50% and as high as 90% when testing their e85, which will give big differences in the end result. I used an e85 calculator to determine how much to use. In general it was about 5 gallons of e85 in the full tank to get to e30.
