How to increase throttle response?

[OrganicMechanic]

I dont know what to Say, but maybe 1 thing you can do is get a special 4 cylinder motor ;)

mmmm....I see what you did there, with the 3 letters

S14 + 1 billion.

What's the point in spending that much cash to find and swap an S14 into the car when I could put that money into the M20 and romp on an S14?

even with a chip, it's not going to happen. I saw 10hp by losing the AFM and going to MAP, and this wasn't a stock motor. how are you going to get 20hp by basically doing the same thing to a stock motor, and then use an off the shelf chip rather than a dyno tune for that specific motor?

putting in a MAF is not going to help throttle response (much).

The problem is not the AFM - the problem is Motronic 1.3 with it's cruddy throttle switch has very poor acceleration enrichment. So when you stab the throttle, by the time the computer figures out it needs to inject more fuel, you've already had a big fat lean spike. Replacing the air metering device is never going to fix this. Ever.

The only real solution is engine management other than Motronic 1.3

also, there's no way the miller MAF gives you 20hp. It's a nice product and all, but not a chance in hell.

Not just the MAF makes the HP it is a chip as well, and you are correct about Motronic 1.3 and the T/P signal but a AMM rather than an AFM does improve the response a bit, enough to be noticeable.

There are other reasons to do this as well.

Just read the info on the GenIII. Sounds really really cool.

Discuss.. Interesting information nando.

Are there any reasons why you'd have to use Miller's ECU? I'm sure if enough people buy this (seeing how it's so cheap), some people wouldn't mind making custom chips...
I don't see what's wrong with using aftermarket chips though, like Jim C or Mark D...
But I guess I shouldn't be speaking for them...

Yea, I'd like to know if I could save the $100 or so on their chip and keep my Dinan.

Just e-mailed them about it.

definately looks interesintg. let me know how this goes.

What's your current mod list look like?
Just wondering where you'll be coming from.

The cars I'll be tryng it on range from bone stock to insanely scewed with (but all 2.5 m20s) maybe I'll do a whole writeup in that new forum.

Hmm, looks like he didnt go through with it?

Was mariano saying he fit a MAF to his eta?

Miller Gen III comes to $378.19 shipped to California UPS, I'll let everyone know how it goes, I may even retail for these guy's.

I talked to them about it a little while back and the possibility of some other things (R&D) but I like the info I'm seeing on their new unit so I'm going to try it out and see.

Link?

Although im guessing this is of no use to my eta

I was just reading about someone with an ETA looking to do the same: http://www.dtmpower.net/forum/e30-3-...i-options.html
