Arai post-FPs interview for Japanese press
http://www.f1-stinge...3/13/055357.php
Actually quite long, so just rough translation
---
Our usage of MGU-K and H isnt suited to this circuit at all, time is very poor, so right now doing strategy meeting reviewing data and working on various things
FP1
had problem in control data for air intake, same issue for both cars
not hardware problem
control data error that would lead to hardware problem, so decided to stop early to examine data thoroughly
FP2
(on Kevin's crash) what he told. he was running quite fast at S1, just about to up the pace but the rear broke and lost control
(on Jenson's "loss of power") it went into "power save mode". There was error in data, so no point to continue so stopped a bit early.
(on power save mode) it was not trouble. Data setting was a bit loose, or threshold setting was a bit wrong. There’s certain threshold for safety, and data wasnt optimized for this circuit, and some figures exceeded the threshold during long run, so it went into safety mode, as it should.
(PU itself not full power yet?) Not at all. Not able to use power effectively. Power allocation isnt done properly at all, so resulting in power loss somewhere in the middle.
(not being able to use ERS well?) that's right. Circuit has many corners, so we're not able to use power properly at all yet.
---
(what do you think of Merc?) Amazing. I knew they were fast in Barcelona already. For us, it's about how much closer we can get to them. Lack of preparation during testing affected us badly, so tomorrow we'll try to make proper running.
(what u regarded as most important?) Allocation of MGU-K power. How to recover and how to use it. It's like, "it's no good to spend this much with my salary of this little, isnt it?" or sth like that. We have to be able to manage the account well, otherwise cannot win the race.
(allocation of energy?) Right. After in and out, we're in red, sth like that. We're trying to find the way to better manage it by analyzing data. We're aware we have to do a lot better about it.
(lack of running during winter testing is the cause?) Yes. Also difference of characteristic b/w here and Barcelona. Drivers are figuring out how much you can late brake and still adjusting things while running. Matching bw drivers and hardware/software hasnt been done yet at all.
(any hardware trouble?) None in particular.
(so it's about polishing software side?) There's no issue in software itself, but nature of data optimization is "the more you do the better it gets" surely, so, feeling shame about the lack of running in pre-season test.
(think can finish the race) Car itself has no issue, but to make the car competitive is another and that's what needs to be done tonight and tomorrow.
(suppose u can finish the race, how many % you'll be able to complete jigsaw?) we see the whole picture in mind, but starting from 50% is team's view, we know the final picture and what to do to make it better, but for some things we need more time.
(can see car's true competitiveness in Q tomorrow?) Dont think so, we are far from 100% of performance we expect yet.
(control data can be improved with no end actually, but time is limited) Not sure how long it takes to review the whole data, but analysis is being done real time in Sakura, which is incredible. Dont feel the distance, this is so intriguing and exciting.
(on time difference) we have to work regardless of time zone. Was tough at Sakura for Barcelona, but here in Melbourne it's only 2 hours, so it's a lot easier.
Not thinking too much about lap count.
(could gather data you wanted?) Yes, enough data.
realize the importance of time and timing. You have make quick judgement on whether it's time to run now or not, the importance of the dicision making is very different between testing and GP. We lost our touch in that since 2008. Communication bw Mclaren is very good, so we're working together to advance things while chatting, so we're not so worried about that. But we realize we need more speed. If we can do that, machine should get faster too.
