That works for a P38L but I asked about the P38J.. They're quite different in the maneuverability department (38L has boosted ailerons, the 38J doesn't) so now you have another key to factor in when drawing a engagement between the two.
There isn't really all that much difference between the maneuverability of the P-38L compared to the P-38J. All that I said for the J also applies for the L.
The 38J has to dictate the 190 with a lot of nose low maneuvers to build speed and difficult high speed shots for the 190.
It all depends on the kind of fight. If you're avoiding the A-5's BnZ attacks, then maneuvers like Low Yo-Yo's to meet the attack to build up E while avoiding the attack is recommended, as this give you sufficient energy to follow the attacker in the vertical for a quick shot.
The 38J won't out roll the A-5 so to counteract that you'll want to fly using nose low reversals to make it difficult for the A5 to get a good gun solution and to gain separation and E if he's BnZ'ing you. If you're familiar with ACM you can go from a nose low pitchback to a barrel roll and work for angels and catch a good burst on the A5 if he tries to extend and climb for alt.
Take the fight in the vertical, it will help negate the roll rate advantage of the A-5. Use vertical angles if in a turn fight, get the fight slow and now matter how much of a roll rate advantage the A-5 has, it will not be able to use it effectively if the fight is at low to stall speeds, where as the P-38 will be able to dance around the A-5 like Nijinsky.
Despite some other post to try and show the contrary, there isn't really a speed range where the A-5 has any sort of significant advantage over the P-38, unlike planes like the Spitfire or N1K2 where at medium speeds they'd chew a P-38 up. The same cannot be said of the A-5, the only time an A-5 is a major threat to a P-38 is if it comes into the fight with an overwhelming energy advantage and/or altitude advantage.
Like I mentioned in my other post, if the fight degenerates into a rolling scissors fight on the deck, the P-38 has the advantage if it can get it's flaps out earlier enough to slow down enough to keep in back of the A-5. If the P-38 didn't get the flaps out quick enough, things can get a little tougher but the P-38 pilot can still force a reversal by using it's slower roll rate and better slow speed characteristics to force the A-5 out front. Also, the P-38 also has the added benefit of still taking the fight into the vertical and using maneuvers like a stall loop to get a quick angle inside the A-5s slow speed turn.
It's a interesting engagement indeed and IMO it boils down to the knowledge of both pilots on ACM, E management and SA.
I honestly don't think so, a far more interesting and better match up for a P-38 (any model) would be the Ki-61 or the Ki-84. I've never felt any of the FW planes an "interesting" match up for the Lightning.
