Yes that sounds right, it's a byproduct of the logic that the JB4 will always "attempt" to add 4psi regardless of pedal input. But you can only make more boost under heavier pedal input anyway.

hey Terry

is map 6 usable on type R? I can select it just not sure if active. I think I got wrong obdII cable as too short but so far so good. I tried both map 1 and 2 with no problems. I have been on civicx forum there is a bit of h8 for jb4 there, I'm trying to make them believers.

Yes map6 is active and can be used to manually set profiles. The limiting factor with the R is fuel pressure though.

On OBDII tuner goes on the driver side so the cable should reach. Photos? We have a longer cable too we can send if needed.

Ahh makes sense. Normally AU gets the longer cable anyway. Was your cable 4' or 6'?

It feels like its lagging or idk what it is. but once it passes 4k its normal. is this boost lag or maybe my 93 gas? or is this considered boost lag?

So i started experimenting with different fuel mixtures, e20, e30, e40.

E40 proved to be the most effective, no more lag seems like it was not the fuel pump but the octane, Heck I ran it on map 3 NO ISSUES ran like a champ.

Mishi intake, **, JB4

Surprised the fuel pressure is holding up on R!

I think the max boost I've seen has been 22-23psi with E40. In our car group (TYPERSOFSOFLO) we have multiple type Rs runing 24-28psi with stock fuel system but they are FBO, running hondata, Ktuner, ect.

In all E40 is the way to go. Map 3 is great

Yes with the flash tuning they can probably set the AFR a lot leaner to try to get away with it. We're limited by the factory like air/fuel targets with the JB4. Which are richer and more conservative. But also hits the fuel pressure limits earlier than running leaner.

Lots are always a good idea.. The TypeR we used for development was not very E85 friendly based on fuel pressure. Your mileage may vary.

Default Issue at track - 06-19-2019, 06:27 PM

Hello Terry can you review these 2 logs from today. Tried Map 1, 94 octane. On the longest straight I come out of corner in 4th at about 85kph, go from 3000rpm to 6000 full throttle then shift to 5th and continue full throttle up to 190-195km. Car would jerk on map 1 in 5th, as if car was running out of gas. Came in, switched to map 0. Attached that log for reference. No issues in map 0 all day. Can you confirm what the issue is? Do you see it in logs. And do you think we can possiblyb do a custom map to work around issue

Is there a specific timestamp on the map1 log you noticed the issue come up so I can focus in on the details?

The JB4 is doing everything we want it to be doing!

All octane are supported. There is map6 in there for customized mapping. We've got WMI support for those who want to run it, ethanol sensor support for those who want to run it. But most JB4 customers are the install a tune + intake, and enjoy the huge power increase sort.

What are you looking for us to improve with it? If there is a false alarm error fault then of course that's always a high priority to fix. Not aware of any of those. Error codes indicate a physical issue that needs to be corrected normally so share the code and we can help you resolve the issue.

What we really need a larger JB4 Honda user base to justify the expense of additional advanced feature development. That should come with time.

Unhappy Problem - 06-24-2019, 04:49 PM

Terry then my problem is that I'm from Mexico and I only have 92-93 octane gasoline. Do you say that I can use all the maps with this octane without problem? or put some octane additive?

Start with the lower maps and get a log. Post the CSV file here so we can evaluate for you and let you know how to move forward.
