Miller WAR Machine 24v Rendition

Arguing about injectors aside, when can we expect this to be available? My swap is up and running now, minus exhaust till everything for it comes in. I have 21.5# injectors and the 540i MAF, so I'm looking for a chip. I don't mind trying something new. I will have access to a friend's dyno once my car is street legal if you send out a batch for beta testing. ;)

If it ran rich then it was tuned too rich, doesnt get any simpler than that. I have 42# injectors on an n/a m20, & I can make it run as rich or lean as I like with the tune.

Basically unless the 21.5# are undersized, there will be no difference if its tuned properly.

If its tuned for the injectors, it wont make any difference in power. That would only be true if one injector was undersized. Basically, within the limitations of the injectors response time vs the minimum pulsewidth at idle, its not really possible to oversize an injector as long as you can tune for it.

For a 21# vs 24# injector, the difference in pw will not be very significant at idle, and it will be even less at WOT - perhaps a few tenths of a ms. even an injector twice that size would work fine if it responds fast enough (and actually, a large injector is easier to time precisely than a smaller one).

I guess, I'm going off my experience with both a TRM chip tuned for the 24# and a Conforti chip. Both ran pretty rich up top!

Granted they were both off-the-shelf tunes. However, I ended up having my car dyno tuned and we made more power with the 21.5s in there and it had much better AFRs up top.

I know Dan will work his magic on the dyno, but I'm curious to see what would happen if both injectors were tuned with the 3.5" MAF to their full potential.

It will allow us to offer a 24# 3.5" MAF tune regardless.

I guess so. No sense in spending the extra money on injectors that hurt top end power. I'd like to see Dan tune for both sized injectors and show the results.

The s52 21.5s would be a better choice for a non-cammed motor. 24# injectors have proven to be overkill on most non-cammed s50s and s52s, let alone an m52.

Any updates :)

The 3.5" MAF tune will be done this week. We are waiting for the 24Lb/hr injectors to arrive so we can do all the tuning on one day. Our dyno has been pretty busy the last week so we hadn't had time.

Any updates :)

Did you weld those tips to a regular magnaflow muffler or do the offer them with the slant in tips?

Those are welded on, the muffler did not come with them like that as far as i know.

[SkiFree]

Looks good, any idea on turbo size?

Let me know how I can help.

^^Would love to hear a sound clip of that!

Want, where can I buy? Make me one...

It will help with further mods . It is like the 19# injector swap on the M20, useless until a point, but everyone seems to do it regardless.

True. I should have added the 21# or the 24# injectors that people usually pair it with. I guess all I'm hoping for is a real gain, my motor has a lot of work done to it but there's only so much that the 2.8 can do without boost...and I don't want boost :D
