i have a 89 240sx with a s14 ka24de-t... the only modds done to it is that it has a bare min. Garrett T3 turbo set up "no intercooler", 255 fuel pump, z32 maf, 3inch turbo catback, and a 8:1 FM... i was wondering if anyone can tune my stock ecu for these mods and also chip a 2-step launch control... "the one that the sti/evo has, i love the way those sound". im planning to put on some 530cc injectors soon too...

if any of u guys can tune this for me let me know how much or if u know who can do this for me...

i was thinking eeprom

well first off GET AN INTERCOOLER. idk about u guys but usually u cant "tune" a stock ecu. atleast not for mazdas. get either a piggyback or some form of standalone. do not put those injectors on till you have someone tune for it. street tuning is ok but i would recommend taking it to a dyno and tuning it there.

My comment was fully directed at the questions you were asking rather than what was on the car.

I'll spend my precious time and answer your questions in one post.

1. Turbo's generate heat. The air going into your motor will be nice and hot. Motors don't like hot air. Get a fucking intercooler.

2. FMU's are the cheap bastardized way of increasing fuel pressure to account for forced induction. It's like hiring a hooker to lose your virginity.

3. You cannot simply "tune" an ecu. You will need a daughter board if you wish to chip it or a piggyback or stand alone.

4. Wanting a 2-step for the sound of it is by far the most ricer and stupidest thing I have read in a long while.

5. An evo sounds like an evo, a sti sounds like an sti. It's the characteristics of the motor and exhaust that make up sound note (especially with the boxer motor in the sti). You will never have a 240 that sounds like either. Get over it now and stop sounding like a 14 year old that hopes they get a 240 in 2 years.


If you want the super cheap (yet still proven to work) way to go about getting your shit running then follow my instructions:

1. Pick up an intercooler and piping. If you get a shop to do the piping and a FMIC from ebay shouldnt be more than $300 (probably less, havent shopped around for those in the past year or so but for my build I got top end and it ran me 450$).

2. Pick up a safc-ii. quite possibly the most terrible piggy back ever, but it will get the job done for your needs (since you dont seem like you will run more than 7 psi). Should be somewhere in the 100-200 range.

3. Get SR 370cc injectors. Gonna cost again 100-200 i think.. probably cheaper though.

4. Get a professional tune by a trusted shop. On a safc-ii should be no more than 75-100$ for a full tune on a dyno.

the reason why people run intercoolers is because it puts colder air in the engine by something called charge cooling. by nature turbochargers and superchargers emit heat. think about it. you have a fan spinning. what is it doing? pushing air molecules around. now when you start moving molecules around what does that do? it makes them hot. and they are being compressed so that contributes to it being hot. when air leaves the turbo it its about 250 and 350 deg F. do u really want 250 degree f heat going straight into your engine without any cooling?

an intercooler lowers this temp. and reduces the chance of predetonation. please do not run ebay turbo's or blow off valves. and please do not try to tune the car yourself . take it to a reputable shop. not jose who knows about civics.

i dont recommend ebay intercoolers they are crap! get a greddy or blitz or so its better and easier to install. dont install injectors yet until you have a good EMS.
