    M20 b2.5 war chip

    I just received my Miller PSIK and WAR chip. I was wondering if anyone with a similar setup to mine has been playing around with their tune.
    I just rebuilt my 2.5 m20
    stock pistons
    Bimmerheads ported head and Bimmerheads 274 cam
    I.E. rockers
    I.E. crank scraper
    Slightly ported intake manifold( runners have been opened slightly and port matched to head. Port matched gaskets obviously
    M20 I throttle body bored out with throttle plate to match( can't remember exact size but it is definitely larger than stock)
    Stahl Long tubes with High flow (Magnaflow) cat, 2.5" pipe to high flow muffler
    Stock injectors
    Looking for a good performance tune to start with and a good economy tune for when I'm stuck in traffic and can't enjoy performance upgrades. I see a couple tunes in the tune cache on the WAR forum but nothing for an m20 with a ported head and cam and stock injectors.

    I posted over on the WAR forum and got a response back about what tune to use. Miller (Brody I believe) recommended upgrading to 19lb injectors and starting with a tune they have in the "tune cache" for headers and a high flow exhaust. He thought my stock injectors might be up to the task but that the lager injectors would definitely benefit my combo. I won't be doing the MAF conversion until I can set up a date with the dyno shop here locally. There is a guy here in Elsmere, De who has tuned several cars with the WAR chip and he seems to be pretty competent. Before I change it up I'll be getting some degree tape and marking my balancer so I can chart the ignition curve with my timing light at 200 rpm intervals, just to get an idea of how much total advance and when it comes in. Any other recommendations on what to study before doing the swap. I have a wideband sensor so I can keep an eye on the afr. I will be installing this and playing with it for at least a couple weeks before I take it to the dyno.
    Once I get a decent tune and some dyno results i'll be happy to post them up. I really wish I could get some dyno numbers now before I do the Miller PSIK, but I can't justify the $$$ just to post some numbers.

      Talked to Mike at E.R.T. today, turns out he is a dealer for Miller and he quoted me an extremely attractive price to put my car on the dyno and get some numbers before I perform the PSIK/WAR modification. So after xmas I'll be headed to his shop to get a baseline horsepower and torque figure. I'm really interested to know what my current numbers are and what I end up with after the Miller stuff and the injectors.
