Educated Hp guess help.

yeah, he could bump up the fuel pressure to 3.5 bar and keep his stock injectors.

hmm, i know a really good local tuner. He does Gentani cars. But it would be about 200$ for a tune. I guess i can save money for the tune instead on the 19lbs injectors.

[nando]

$200 for a tune is cheap, if he's actually any good. dyno time here costs $100 an hour, plus $50 setup. that's without a tuner to guide you.

We know the guy, he is my brothers friend. Plus we are also good friends with the Gintani shop owner. i can prolly get my car on the dyno for less than 50bux.

Mega Squirt or WAR chip?

[nando]

there are advantages and disadvantages of both

war chip-
pros:
easy to set up
relatively cheap
MAF conversion is easy
you only have to worry about timing/fuel maps
cons:
stuck with Motronic 1.3 hardware limitations (single coil, batch injection, no boost support, smaller injectors)
no real datalogging
no support outside of miller
closed source - if miller disappears, you're stuck.

megasquirt-
pros:
control over everything
highly customizeable
not stuck with limitations of the stock hardware (cop/sequential is possible now/soon)
wide ranging support - used everywhere
MAP sensor (no intake restrictions)
open source - constantly being updated
cons:
harder to set up (steep learning curve)
you have to tune everything (that means learning)
costs a bit more
improper installations can lead to issues (bad wiring/soldering)
the amount of options/possibilities is confusing to new users

if you want something tomorrow, get the WAR chip. if you don't mind spending 6 months reading and learning before you dive in (to avoid getting lost because you don't understand how EFI works), then get megasquirt.

[E30Pedia]

yea, i am leaning towards WAR chip. the tuner said working with the mega squrit is a headache.

[nando]

it is if you don't understand it. especially if your tuner doesn't like it, then get the WAR chip.

[E30Pedia]

Hey nando thanks for all the help man

Seriously appriciate it:up:

[LowR3V'in]

It's all pesonal prefrence.
You like to have full control of the ecu and see exactly what's
going on? :)



Cool thing about MS is that tons of M20/M30 guys
are using it so you got... TONS of support for settings.

Back when I first used it, I got a really really rough msq from somebody.
Drove to work 20minutes after plugging everything up. Cold starts where terrible, no ICV, VE was a mess.

Now people have got everything down. Basically get a good msq and you'll be in the ballpark.

Now there's VE anylize live, so it autotunes while you drive.
Probably get a clean factory like VE in 30minutes.

Not to mention many many awesome features and a datalogger.
You'll probably get about the same hp +/- with a chip vs ms if you're stock (ish).
