car tuning

collins590 · 11-27-2004

im running a 240sx in online drags and im having a bit of trouble tuning it and getiing my times down on the quarter. im racing against guys running 21's on bayview and my quickest is a 22.75. I was wondering whats the best setup or if you dont wanna give away your setup let us in on what to look for in tuniong a car.. like to you need to softn or tighten suspension, around what is the best gear combinations and so on.

thanks.

Do you have a fully customizable tranny? and if so, what is it set to?
As for ecu and turbo all I can say is to make the torque/hp curve the highest in the rpm range you use the most (for me around 6-9k) I'm sure theres better methods tho.

All you actualy need is quick trasmission, ecu and a turbo...
if you have all the upgrades of the engine of course...the trick is that at low speeds you should have long gears, at high - short...only works when you have enough horsepower under that hood of yours... if you don't... make gears short...
ECU and turbo settings a performed like this - just take the rpm's you don't use...and lower the HP on those...the rest of rpms will automaticaly get more hp.... I actualy set the highest hp starting from 5000 till redline...so go knock yourself out...

i was doing the exacr opposite.. i was putting the low speed gears shorter.

Can somebody explain how to get more horsepower please? I can only tune out about 5 extra from playing with the ECU.

Hey, U know what, I've tried maxed out Nissan 240... the first gear was up to 103 kph, and I scored 1.23 sec from 0 to 100, and using nitous - 1.02...[ talk about realistic...jeez]
and abot more hp...install upgrades...but if you still need more...read my short instructions above...but 5 extra? not much...cu usualy gives me from 15 to 25 kw of power...also try playing with turbos...and another thing... IT IS GOOD TO SET MAX PERFORMANCE OF ECU AND TURBO ON SAME RPM's
P.s: Collins, did it work?

it dodnt work well with short gears for low speeds and longer for higher... thats what i thought you had to do but i could onliy get around 9.52 secs on the 1/4 mile while others are getting around 7 seconds. When i get a chance ill fix it to the toehr way around, i hope i can get wicked times.
