ok, so i looked at the paseo cynos catalogue and i cant figure out which chip to buy for my car, a 1996 paseo. I've got a Weapon-R intake, Pacesetter header, magnaflow high flow CAT and muffler with 2-1/4" custom bent stainless piping between the cat and muffler. i want a chip that i dont have to recode or code anything, because i really dont have the time to do it till the summer. I am taking a C++ course in college and am doing really well in it, but i still dont want to have to learn a whole new programming language. i'm pretty sure with a little tuning on an after market chip, i can pull out between 10-15 extra ponies under the hood. if anyone has advice please let me know.
First off, you will not pull 10-15 horsepower out of retuning your car. To be honest, your lucky if you got that much from the mods you have done so far. Not trying to belittle you, its just not that easy to make horsepower.
In all honesty your stock ECU is probably doing a pretty good job of keeping air/fuel ratios close to what they were stock. I wouldn't even bother with a piggyback system. You just haven't altered the engine enough from stock to necessitate it. I have all you have done and more, and I'm still running the stock ECU on my Paseo without any hiccups.
FYI, you don't have to learn a programming language to retune cars with piggyback systems. Its basically like filling out a spreadsheet for different engine/sensor situations.
yeah i meant overall gain on all my upgrades, my bad. and the only reason i wanted to get an ecu upgrade is because a friend of mine pulled off a 30 hp gain by mapping out his curves on a dyno here at school. and he was running a 1.6 liter vtec NA. just trying to get the most i can with what i got. would an ecu upgrade be able to give me any gain on a DIS system?
If you are staying naturally aspirated I'd recommend the emanage blue, or ultimate if you are feeling spendy. In order to get anywhere near a good amount of power your going to need fuel and ignition control and the emanage blue is the cheapest I know of that does both.
ToyotaTechGeek, I'd agree with you about older engines, but not newer ones. Gaining power used to be easier due to engine ineffeciencies. Modern fuel injected engines with all their wonderful sensors can and do monitor changes fairly well (of course this changes from engine to engine). For example, if you open up the exhaust a bit and the MAP sensor knows because your pulling more or less vacuum and it adjusts your fuel and ignition. Same goes for intake modifications. Unless the car is horribly tuned from the factory, you aren't going to see amazing gains by going with an aftermarket fuel/ignition computer.
so what do i need to tune my car using the e-manage blue? i have a dyno at school and i have a laptop. is there any reason i need a tuner? especially since it is like you said, "like filling out a spreadsheet." is there any reason i couldn't do this myself?

yes. an experienced tuner can help to reduce the chance you'll experience catastrophic failure in the process of tuning.
Bubspaseorules, in order to properly tune your engine you should bring it to a tuner. No offense intended, but its kind of obvious that you don't know exactly what your doing, and that is fine. So, pending you reading up a lot on engine management systems and how air/fuel ratios and ignition maps effect engine performance, I'd highly suggest taking it somewhere to be done. On top of the emanage you'd also need a few fairly pricy sensors/gauges to deal with the retuning. This isn't something you should just be tinkering around with. This is the key to having your engine running at peak effeciency. Like ToyotaTechGeek also mentioned it will reduce the chance of catastrophic failure.

I think your skewing things a bit here. I'm talking to a guy who slapped an intake, header, and exhaust on his Tercel. Your talking about a pretty highly modified turbocharged engine. The two are a little different.

no, it's cool. yes, i'm getting into semantics, so practical application is going to be different. however, the blanketed statement made it hard for me to resist!
so, an experienced tuner is going to know how to manipulate certain parameters and find gains within the powerband easier than a novice with no experience at all. also, a competent dyno operator will be more than paramount in your quest. overall, don't expect HUGE gains as eManage is only a 'true' piggyback (better than S-AFC, ITC, etc but doesn't do AFM->MAF conversion or anything of the sort), and it isn't a full stand-alone system. i don't think a full stand-alone system is required here. even going to Electromotive on my 3E netted 'decent' gains, but don't expect it (eManage) to do too much. one thing most forget is that the Tercel chassis was basically an entry-level grocery getter. true, my 'grocery getter' has beaten 911's and such on track, but i think it was mostly attributed to the nut behind the wheel~why do i bring-up the Tercel? because the hatchback became the platform for the sportier, two-door Paseo .

ok thanks for the awesome responses. i will probably end up taking the paseo to a tuner anyway, because catastrophic failure isnt an option when you only have one car. and thanks for mentioning the emanage, because i was having a really hard time finding the ecu stuff from the catalogue. l8r!
