I do have a silly question how can you have lean burn on a vetec e motor without using vetc engagement? If you read clearly I said that it is base map similar to a p07 it is more leinent with leanburn. Even with 02 delete it's worthwhile and by definition a custom tune.

My understanding is the HX vtec scheme (VTEC-E) is very different from what's in the other VTEC cars. HX has the 2nd intake valve cracked open very slightly in non-vtec mode. I think it would be in that state in lean burn too. I think the idea is to aid swirl and combustibility. Maybe also aids cooling. Also I read the HX's VTEC-E has a VTEC mode where all valves open - but this kicks in at a much lower rpm than on the EX / Si versions. It seems to kick in around 3000 rpm or a bit higher in my car.

Anyway, I'm very interested in the work mugen is doing. We have to give them credit for concentrating their efforts on the ECU tune and swaps. We have lots of guys here with expertise in all other kinds of eco mods!

Lean burn can be done safely without an o2?

What about states with tailpipe emission tests? Swap back to stock ecu or would it pass still?

2000 HX stock gives me LB in 3-5th gears currently, with constraints. More LB time would be welcome...

Do you guys have any cars currently up for sale?

Last I heard, they hard three cars up for sale.

LB works already in 3-5th gears. Not sure exactly what you are talking about adding it to 3-4 gears.

I am not sure i want LB always active in 5th. Also, have you done research on how this long-term effects the cat, EGT's, ect? I would also like to see a dyno sheet with WBO2 readings vs RPM, with LB engaged.

What price point are you looking at now?

Also, with a p28 ecu the car woln't be OBDII anymore, so one would need to retain the factory ecu to swap back into the car for inspections.

What software package are you using to tune the ECU's?

Would love to see a LB active light or indicator integrated into this package, or possibly even a way to adjust the LB engage parameters.

My biggest gripe is that LB woln't engage at 45 mph in 5th. Would love to be able to keep LB active down to about 1500 rpm in 5th, and get rid of the 80mph kickout. But before I felt safe driving with this, I would like to know the reason honda integrated these originally and ensure that there isnt any long-term detriment to my engine or accessories.

What about states with tailpipe emission tests?

And more importantly: What about actual real emissions?

It is suposed to bring us more consistant lean burn in a wider amount of RPM's. They mght be talking more for the HX as it is much more picky about lean burn, but they have made maps for both the hx and vx.

They really can't say anything for your car specificlly. It might still pass or it might not. It might not pass with the stock ECU in your car either. Just depends on how your car currently runs and the condition of its emmision items.

I am sure these results will vary depending on the car? But I am sure it is not as bad as a Hummer... lol
