i just purchased a JDM ca18det mines ecu tuned for

-z32 maf
-stock injectors
-.9 bar
-hks gt2510 turbo
-FMIC, full exhaust,intake bov VENTED/Re-Circ.

i've bveen told that i cannot boost the reccomended level of this ecu re-tune w/o the apropriate gas type. gas type meaning japans mid grade to high grade.

has anyone had any experience with these and what is your feedback. i am in no rush for the info becasue none of the parts are on the car yet. jsut wanted to gatehr info before i got myself into a sittuation after install.

i think its tuned for like 100 octane isnt it? i was told that Mines runs a lot better with 100 octane...

well, my Central20 ECU seems to run fine on East coast high test, and back when i worked at a certain sr tuning shop... there was i beleive a Mines, or some jdm tuning ecu that we used on a customers car, ran perfect. so, i'd say your high test with maybe a can or two of octain booster should be fine.

read about some guy on nico with a mines ecu and everything else stock (think he had a intake and exhaust, not sure). ran low 14's high 13's. thats great. anyway i think 100 octane in jap is the same as our 93-94 here. well thats just wat i've read.

on which motor did he get these results?

members on this forum say to stay away from octane booster... since the o2 sensor will eventually take a dump...

93 octane pump gas or even better gas...

we dont have 93 in my part of cali. we do have 100 and 110 at the race track which is like 3 minutes from where i stay

Laguna Seca Raceway for yall who dont know. its like near 6.00 per gallon. what mixture on 91 and 100 can i try to get an appropriate octane level which its safe to boost on.

yeah I remember when I was in norcal (mtn. view), there's only 91 octane pump gas...

yeah mixing up race gas with pump gas sound cool - as long as it doesn't cause problems for you driving back and forth...

how will octaine make ur o2 sensor go bad? thats f'ing stupid and a rumor. octain booster just make your ocatin rating go up 1 point. ex. 91 oct. + 1 oct. point = 92 oct. on a daily basis octaine ratings fluctuate on decrease... so i'm sorry the pump will fuck your o2 sensor up too...geez people.

^wrong. octaine boosters make it go up a fraction of a point. u will need lots of em to get it up to 92. best way is toluene or xylene if u wanna get it up high. theres a thread of how to i made called "race gas tech"

i heard the NOS octane booster is the one that makes it go up 1 point. the rest is a fraction. i also heard that they make your combustion chamber turn red or something like that. again rumors, i think. the results were on a sr20det btw.

Okay, there are a post on zlivia.net, which contains a picture of an O2 sensor's tip being red. It was determined caused by octane booster. there are safe chemicals out there which doesn't harm O2 sensor. IIRC, NOS octane booster is not on the list.

well, I guess I need to pull up the thread via the search button.

EDIT: here's the thread. The pic is the spark plug, not the O2 sensor, however, the O2 sensor will have the similar color charateristic like the plugs due to fuel addictives.

You can use an S afc to tune more conservatively, or play around with base timing, you won't know how the ecu is running until you get it on a dyno or have a wideband.

Well it all depends on what kind of race gas your running. If you stay UNLEADED, your o2 will be safe. The moment you start suckin on leaded gas is when it starts fookin up o2 sensors. I know cuz ive run 5 gallon 110-116 octane leaded mixed with regular 91 gas. Got bout 5 tank fulls before my o2 went crap and mileage went down the shitter...and this was on a brand new fattie blacktop o2 sensor. Toulene is a cheap alternative but the downside is that it has a tendency to eventually rot your fuel hose lines.

wow. i hope you're runnign this ecu on track only brannen because mixing $6/gallon gas with 91 for street use could be expensive..

like stated above...go use safc to piggyback on it and add extra fuel.

xylene is cheaper...kinda like 9-10 bucks for a gallon of 118 octane vs 6 bucks for 100 octane

wat about the thing about the octane ratings and that in japan their high octane pump gas is same as our 93?

Look up octane, pon, ron and mon on google. To put it simply PON (the octane rating we use in america) is generally 4-5 points lower than RON rating (which Japan and Europe uses).

It's turning into an octan thread...

but from my expereince (I have an old in the Tech forum) the NOS ocatane booster (blue race version) was not very beneficial for my car. It made my new NGK plugs turn orange (didn't affect performance in the long run, but still annoying), and gas mileage was crazy low (~16-18 i'd say). It was either the octane booster I put in or the gas I used (Mobil).

thanks TurDZ for the clarification. I have quoted your thread above to show the shittier side of octane booster...

getting an SAFC and dumping more fuel will do nothing but bad. It will in no way eliminate the detonation/pinging caused by to agressive of a fuel map.

have you gotten cams for your KA yet??

Do you go to UCSC RBS14? I've seen your car before. Back then it had a giant panda on the side and white spray paint on the wheels with overspray on the tires hahaa.

so what do you suggest? finding someone with eprom skills? or send my stokker to mines shop in japan? lmao and have them remap it for us gas which i dont htink they can do. hut hey anythings possible.

stand alone is not an option here.

I'd say just retard your base timing a little bit and see if that is enough to keep it from detonating/pinging.

Ran: Yeah, I got some JWT cams. Love em!
