I just think the article is click-bait. There's literally no change to the LMP2 regulations except aero has been added to the list of things they're allowed to change. To have the headline "LMP2 Subject to BoP Adjustments" suggests it's something new to the class and something that's actively happening.

Yes you can make the argument that 1 adjustment is BoP, but that's a matter of opinion and I disagree that that isn't exactly what BoP is. However the rest of it is just click bait...again.

I generally have no problem with BoP. But I'd like things reported accurately and honestly. Remember that these provisions existed in the previous generation LMP2 regulations as well and were never used despite large performance gaps. That's how much of a non-event this is.
Sorry, we will just have to disagree on that! They balanced the cars performance against one another, period. = BoP.







L.P.

Besides, it does seem that the ACO did have provisions in the rules, they just never have used them outside of the Joker, which was also provided for in the rules from the start.

Joker, BOP, who knows, who cares. LMP2 already has a spec engine, limited chassis and is intended to be a semi-spec class anyways.

Top trolling from LPM2 entrant Alpine here, showing their new road car-based GT4 with their traditional LMP2 race number. A privateer's category, you say?

In an article on Racer, JPM talks about driving the Ligier vs the Acura Oreca, and this may explain part of the reason the Oreca is dominating:

Quote:
“The car is just very different to what I race in America,” he said. “The feeling is very different.

“The traction control in particular doesn’t work well compared to what we have. You’re almost better turning it off and figuring it out yourself. [For] six months I’ve been driving where you can point and give it everything you’ve got. Here, you’ve got to be pretty nice with it.
So the Ligier traction control is aweful, according to JPM. Not sure if the one on the Acura is stock from the Oreca or developed for DPi.

I suspect the traction control is the same in all LMP2 cars. They all use the Cosworth ECU. Acura will have custom electronics for the new engine.

That's it. ACO LMP2 use mandatory spec cosworth ECU and electronics.

Very likely DPi, being powered by engines that develope more torque, have a dedicated ECU.

I wonder if Ricky Taylor thinks the same, also moving from Acura to Ligier.

That makes sense. I would like to hear from some of the folks that have driven both the Ligier and stock Oreca then to see if they experience a traction control difference.

Think it speaks more for the advantage the DPis have over the stock P2s in IMSA.

Well at least for the teams who have developed a good system, maybe not Mazda....

But seriously, how do you BOP that?

You don't, you have to either let go of the P2 formula or seperate the classes. It's not like any of those P2 teams are going to Le Mans anyway.

You make them use the spec ECU in the first place instead of giving in to manufacturer complaining then using the media to shift the blame to the ACO.

I'm pretty sure that the TC mapping was left to each manufacturer to tune themselves and was not a same/same map given to the teams from Gibson. So it's still possible that Oreca have developed a better system.

Anyway, Onroaks problem as always is their lack of aero efficiency which is also apparent with their P3 product.

I know a race engineer in P2 who is currently working on both the 07 and JSP217 this season so I'll find out what the major differences are and why the Oreca appears to be the better package.

The ORECA TC is completely unrelated to what is in the Penske cars that run a completely different electronics system either way. Even when you have mapping freedom a spec ECU tends to have fewer parameters.
