i have an 95 LS with a stock OBD1 ecu not sure what type of ecu it is for my model. but i did a few mods and bold on it like cold air intake, hearder, exhaust, cam, valve and spring, MSD ingition, light wieght pulleys. ect but i havent done anything to the ECU and i was wondering if go get it tuned for all my mods with its stock OBD1? or do i have to get a stand alone ECU..

 

You haven't done anything that would constitue a tune besides MAYBE that camshaft.

 

OBD1 can be chipped, so no need for a stand alone.

And even a 100% stock car can benefit from a tune. Each motor runs slightly differently, especially with some wear and tear on it, but each stock ECU runs the same tune. Dialing in the ECU for the exact engine will result in better power, mileage, and reliability.

 

What cams did you put in?

 

you could use a tune after changing cams

 

i agree even a stock car can benefit from a tune...headers, cam, intake, exhaust... you might be running a little lean... your moving more air... search ebay for or craigslist for a stock P28 computer, then find a decent tuner...someone who has a bit of car under there name..also dont buy into pre-tuned chips..you might as well **** your money away

 

why would he want a p28 computer? he has an ls. his stock computer is fine for chipping.

so yes, op, you should get it tuned, i'm sure you'll gain at least a few hp.

thanks u guys for the input cuz i wanted to know if i could tune it or reflash my stock ecu. but like what chipped do i get... and i need the chip my ecu to retune or reflash it

 

i wasnt really asking if i needed to do one but if it can be done with a stock ecu and what u have to do for u to be constitue to be retune or reflash

 

so what type of P## computer to i have in my stock LS just wondering

 

i dont know...check its under your passanger side kick panel

 

should be a p75

 

you'll need to get your ecu socketed and chipped. i had this guy chip my integra ecu a few years ago, http://www.phearable.net/ . mail him your ecu, he'll send it back to you with a socket and chip in it with a basemap on the chip. you'll be able to drive your car with just the basemap but you won't get max power out of it until you have somebody actually tune it.

 

I always try to stick with external or piggy back ECU's because if you jack up tour ECU your car is down until you can find a replacement but if the piggy back gets jacked you can just pull it out...unless you blow up your motor hahaha

FYI GET CROME!!!

GET IT HERE http://forum.pgmfi.org/

Inexpensive and completely customizable even at a local tuner shop.

 

do u think i should just buy a p75 ecu that already been chipped from like ebay or something

 

what exactly do you mean by "external or piggy back"? in order to use crome you have to socket and chip the original ecu.

no, don't get one of those "pre-tuned" ecu's. get your ecu socketed and chipped, and have it tuned by somebody who knows what they're doing. with those ebay chips you'll probably lose power.

 

yeah i was wondering what u talking about so u saying it didnt have to socket and chip your ecu to get an external or piggy back..

 

thanks for the head up cause i was thinking about getting one but thats why i ask around first

 

External or Piggyback like a greddy emanage or hondata in this case. Crome is just an alternative to sending your ECU off to someone. Its also cheaper and more easily modified at a shop or home because the software is free. Sorry I didn't make that clear before.

 

im pretty sure a "external" piggyback is like Super-afc, V-afc...ect. ones that dont have you open your ecu... hondata is internal so is crome. i have crome softwear and neptune,i tune with both. very effective.. if you know what your doing. if you dont you will destroy your engine...make sure you get someone with a good rep to do your tuneing....



DO NOT BUY A PRETUNE ECU OR CHIPSET

 

chipping your ecu is a better way of tuning than through a piggyback. as far as i know crome can do everything hondata does, except the software is free. and yes, you're right, if you have the tools and knowledge to solder with you can buy the parts and do it yourself without mailing your ecu out. i chose to mail it out just so i can be 100% sure it's done correctly.

 

External like the AEM EMS, or Greddy E-manage or E-manage ultimate the two you mentioned are for monitoring and tweaking your AFC not engine tuning, though they help.

 

Hey found this if you got the $$$ this would be safe haha

All pre-assembled HONDATA ECU

 

fyi: the aem ems is a standalone, while the greddy e-manage is a piggyback. 2 completely different things. what's an afc? a/f controller?

 

to make it all easier on yourself... get the ECU chipped with hondata. And if you dont want to send your ecu out and need a spare. Either the p-75 or the p-28 will work because any good tuner will know to turn v-tec off with the p28 (which the hondata allows you to do). This also keeps you ready if you decide to do ls-vtec anytime soon. You wont have to get it chipped again just retuned. Stay away from standalone on that set up. And chrome works off of mostly basemaps which differs it from hondata.
