Default SCOOBYCHIP?? eprom?? 93-96 wrx

for the 93-96 jdm wrx.....hmm i wonder what other think of this?

he says they are scooby chips/ eprom stage chip.

just thought id share and see waht others think, bc if this were to seriously work for my Z4, then i'd be all over it for that price.

ROB, i know you are pretty much a subie guru, what do you think about this chip? scam or whatnot?

if this works it would be great fo us older wrx guys, who cant afford the apexi PFC, or any other standalone.

thanks,
Andrew

here is the link to the chips..

You have no idea what is on that chip, if anything. A couple of years ago I ordered a "scoobyecu" from a guy in the UK. The first one never showed up, the second one was blank I wouldn't trust my engine to a random tune from a guy in Latvia.

Since then I have educated myself so now I do my own. If you are looking for an Eprom upgrade, send me a PM. Or as JDMFLCL said, PolarPerformance in the UK is reputable.

how can this lil cheap thing do all that stuff...
that is stuff that a PFC does..

raises boost to 16psi..
remapped fuel/timing
faster turbo spool?! *c'mon *
no speed limiter
boost limit 18psi

and a gain of 40-70hp..

and all it is, is basically a plug and play kind of thing...nothing that simple can do all that...

well good luck to anyone who tries this out... or should i say, say good bye to your motor...

** im in the same position in you... cant afford a standalone...im trying to figure other ways to gain power.. and so far Rob seems to be my only solution.**

lols ROB FTW

Chipping an ecu is not new by any means... I would not be so quick to say what they dont and cant do. If it is done correctly by a reputable tuner I would say yes to all of the above. What do you think the accessport does to the newer cars... just flash the ecu(basically the same as a chip but different delivery method). I would agree that a true programmable engine management system is a better way to go if you can afford it, but a chip is not a bad idea for someone on a budget... IF you can get ahold of one from a reputable person/dealer. Further proof... I know many 1g eclipses and talons that ran 11's and some even 10's on the tmo chip with an afc and big turbo/injectors... many other supporting mods etc.. This was before engine management became the big thing. With the engine management... yes alot of these cars went faster, but were definitely NOT SLOW with the chips.

Hey Mead,

Actually an Eprom upgrade can do all of this. Better spool comes from optimizing the boost control solenoid duty cycle map. The stock maps are far from ideal. But I recommend a simple MBC anyway, so it's a moot point for me. Eprom tunes on the early G motors are quite a bit more complex than the open source tuning on the newer motors, so only a few people know how to do this and takes special hardware.

What you get with PFC or standalone is ability to live tune and get the best map for your car. The Eprom tunes are only off the shelf maps that get you 90% of the benefit that a PFC would. I am working on a live mapping eprom upgrade, but won't have that done for a while.

There are a couple dyno plots on Nasioc that show 40-60chp increase after adding an Eprom. Most of the power comes from upping the boost. I have been running my own Eprom for a year now. I run 16psi, hitting est 290-300chp, and commute everyday with 26mpg. I have run a few rally-x races with this setup and also a session at PR 1/4 drags (13.5 with bad 2.1 60'). No blown motor, runs strong.

Right now I am working on tuning for my 550 STi injectors, plenty of power still to be had.

-Rob

And when you get the 550 tune done I'll be the first to pay for it.

I have been told to run STI yellow 550s you need a 97 0r 98 2.5rs fuel rail. Its direct bolt-on.

****ty on the engine. What are the plans for the full build? I am still trying to figure out my issues. It seems really weird how random the power loss is. I am starting to wonder if it is something different than the coils causing the issue
