ok so their is someone who claims to have ran low 13 on a t25/370cc/jdm de+t
on a stock ecu (259cc) and wanted to clear this up already..now i know the answer
from my experience of puttin together turbo set ups.. and its not possible..!!!!
but anyone on the forum have any experience on turboing on stock ecu..

i feel like a noob for this thread.. but lets clear this up.. and yes iv done my search

You must be drunk. I told you I have ran low 13's on a stock ecu, 370cc's, de motor, t25 u12 turbo.

Plus, you know I can drive sucka. 'nuff said.

I think it's possible, but it's also dangerous, why? because the fuel is just too rich and the ingnition too high..

I use stock ECU on 370's for about a year, but I was using SAFC, my car never ping and my bets E/T was like 14 flat, I'm not the best driver though.

When I switched to calum basic, I really felt the difference, she was a beast even on 9 psi, at 12 psi was really really fast and ran 12.85 on slicks, I haven't beeing able to run it at 15 psi because damn slicks just can't hold, they spin in forst gear and by best E/T has been 13's lows.. I broke an axle and a tooth of my diferencial. So, I'm taking care of my baby now, hehehehe..

I have run .. 550 on stock ecu .. for a longggggggggggg time its not the right thing to do but it can be done , if you know what are you doing.

i just boosted my de a couple days ago (stock p11 ecu) and a week or so ago i installed a safc2 with walbro and 370cc and she ran fine and now shes on boost and its really nice but im gonna get a calum once he gets caught up. an safc2 is a good temperary solution until u get a calum or something better

Done this with two different cars......
Stock Low mi U13DET u13 ecu/maf (54C)/ t/25/front mount/ 3inch pipe/ 108+ octain @ 4bar w/ 255 pump/ 12.89 @108mph on slicks
Stock Low mi U12DET u12 ecu/ SE-R maf/ 3 inch full piping/ top mount intercooler! 108 octain+ @4 bar w/ 255 pump 13.19 @ 106 on slicks.....
Hope that helps....... PS. dont try this w/ out fuel pump/ fuel pressure @ 4bar and @ least 108 octain is the key! I've only done this with the jdm ecu's with matching mafs and skinny o2....

Have a Friend that had a 200sx with t25 top mount and 370cc and ran a 2.57 with slicks on 14 psi ran it for a year and a half with no problem sold the car and it went throw 2 owners till it broke. only problem he had was blowing 3erd gear away

i ment stock non jdm 370cc ecu.. usdm 259cc ecu

best answer so far but ..like all the others u used a piggyback style..


ok.... so to end this already...!!!! u cant run a stock ecu!!!!..where not gonna get technical about it .. but no matter how much u mess with the timing or tuning u do it wont run correct.!!!. it will run, but not no low 13s!!

I'm currently running stock ecu on 370's. Car is faster then NA but I'm sure it will be better once a good tune gets put on via Calum Real Time ECU :).

So back to the topic, to run low 13's I doubt it's possible, but just to run and have a quick car, it's possible.

Ran 370cc on stock ECU + Emanage for like a year, with some tuning got steady 12:1 AFR on WOT, perfect AFR's on cruising and a nice 15:1 AFR idle.... Car was fast as all hell with S4 cams and 9psi and got excelent MPG. Also ran 550cc injectors but that is about the limit because the AFR's on idle sucked, WOT was perfect though.

You guys gotta stop thinking on JWT as the only solution for a basic T25 setup.

once again u didnt read the thread !!!! i ment stock ...no afc/no emanage/ aem/ etc...STOCK!!!!!!259cc ecu

best answer ........ "So back to the topic, to run low 13's I doubt it's possible, but just to run and have a quick car, it's possible"<this are the same words i tell individuals who claim to have ran low 13s on stock ecu's
and for the record i have ran a stock 259cc ecu on bb and it smoked like crazy//very bad on gas/constant sputter/ its common sense det compared to de+T is a big difference an American ecu will respond better to na
block with turbo than a complete det ..""timing and ignition maps are different"

No kidding, I have a full DET setup. The car stalls everytime I step on the gas, the car doesn't start right of way, I need to crank it 10 times etc. etc...

I'm just waiting on my realtime, and avoiding driving the car too much :(

Miguel, I dont have proof. Your topic was right. I could never run low 13's on what i had on my old red b13. Yeah yeah, i made it up. I never ran low 13's on my de+t.

Ask the guys who did see my car run Cali speedway back in 05. Ask them what was my exact time. They remember. They wont bullshit you. BFG's and a near perfect R/T makes things happen.

This is what i would like to do Miguel... I'm personally going to buy a b13, turbo a jdm de with a u12 turbo, fmic, 370cc, STOCK ECU. I'm going to copy my exact set-up to prove a point to you sucka.

OPTIMUM LABS.

WHY?

Why?

why?

wHy

whY?

Why would even bother? to run on the stock turbo injectors with the stock ecu? Nothing good will come from it, other than crappy A/F.

Iirc, he ran 13.2 back in 05 with that setup u mentioned.

Also remember his b13 gettin stolen & him putting it back together, I still members that shiet, it was messy too :(

u dont have to buy a b13 u can tune b13 w10 det im doing for someone and share with us the results...
i have a jdm u13 ecu and a stock usdm , ..

ditto, those were the days. i couldnt believe he ran that when he told me. that motor ran hard.

<<somewhat offtopic>>

c'mon. lets cheer up this thread abit...:D

he told you or you witness it?? very big difference between verbal and actually witnessing .. im not denying the car didn't run ..but outperforming a fully tuned det sounds like something amazing....

Juan knew that motor very well... Juan knows i can drive... Juan got a ride on my car several times dude. Why dont you let it go??

I didnt have money back then for tuning shit. I didnt know about tuning period! There is absolutely no reason for me to have lyed! Maybe your tuned w10 yadayada wasnt as strong as my JDM DE with the u12 t25. Lets not go on fool.

I challenge you to a turbo set-up. Build your shit, i'll leave mine with stock ecu, ( fuck afr readings, Its only 300 for the motor) just to prove a point. By the time your done with yours, I'll be finished with several other projects... That car will be sitting for months like the RHD project.
