Re: turbo4age 5.5psi no tune vs. pretty solid 20v 4age
i might look into getting just a new harness online and wiring it up myself and just using MS to save some money since work is getting slow lately.
i bought this MS like 2 years ago, all i remember about it is that its MS1 and its the pcb2.2 with MSNS. Ill give it a try...
and i got the turbo as a birthday gift from my cousin... so it was free.fifty free. i have a well sorted bottom end and the fact that this car only gets driven >2000 miles a year means ill be running 100 octane in it exclusively... so im looking at 20+ psi out of it and hopefully between 250 and 300 at the rear wheels. ill be replacing driveline parts with supra stuff as they break, i kind of want to see what good condition trans and diff can handle.

before you do anything with the ms1, load the good hi res code.
after that, find out if you can do blended mode with it.
then give it a shot in blended if it has it, or speed density if it doesnt.
20psi on a well sorted 4age should make you closer to 350 than 300 whp shouldnt it?
what are you planning to rev it to? and what cams does it have?
you'll **** into the 250 mark, and should make 300 with relative ease.
if you cant get the drivability sorted with the ms1 chip, upgrade to a ms2. you can always sell it again to someone if you arent happy. there are plenty of buyers, and its gotta be cheaper than the haltech and worth a shot.
make sure you use the stock toyota map sense manifold thingy thats on those throttles... hmmm... or is it on the stock throttle to head adapter? not sure.
you want the map signal to be fed from each barrel evenly. if you allow those to mix in a small can on the way to the sensor, that can help keep it even, but also slow the response down (not good.)
there is always plenty of help available on the forums if you can be polite and provide enough info. lots of really switched on dudes there.

Re: turbo4age 5.5psi no tune vs. pretty solid 20v 4age
the unit has an internal MAP sensor so ill be using that with a vacuum manifolfd that is connected to each intake port to even out any irregularities.
im sure itll make more horsepower than i expect... but i like to err on the low side. i made 150 at the rear wheels with NO tune on a stock ecu and maf at ~10to1 afr on a mustang dyno at 6psi... that same setup tuned should have given me around 170 or 180 on the same dyno. now i have itbs, a larger turbo, a "built" bottom end, and itll be tuned... so if the car can take it i should be breathing on 400rwhp. my compression is around 7.5 to 1 so with the right map sensor, fuel, and tuning i will really be able to lean on it... maybe if i break 300 or 350 ill just turn the boost up in hopes to see 400+
so far people have been pretty good to me on here... not to much turmoil. jd has helped me along, as well as several other members with corollas. i have been building these cars for almost 7 years now so mechanically there isnt much left to be discovered... its this damn wiring ----... but once i dive into it i think itll get easier to handle.

make sure you dont exceed 21 psi on that map sensor. you can get an upgrade to 45psi if you need it ;-)

Re: turbo4age 5.5psi no tune vs. pretty solid 20v 4age
thats more or less what i did too :-)
tuned with a valve spring holding the wastegate wide open (wastegate spring out) for 20mins until it ran ok and went ok (circa 190crank hp with 3.5psi)
drove it around for a day, drove it to another city, installed the spring, stayed out of boost till i got some decent fuel in it, gradually rolled it on and increased fuel where needed until it was rich enough everywhere, then drove round thrashing it and adjusting it. total tuning 20m learning, 1hr tuning in boost. a lot longer (not yet done) to get good economy and clean plugs etc etc etc...
