Thread: Do I need a tune?

Stock plugs are the best plugs for them. It isn't necessary to get a tune from such minor mods. Up to you. But you will need some way of tuning your ECU, ie, convert your ECU to obd1 with an ECU and conversion harness.

a load more power midrange. and gain some up top. can do conversion harness and ecu package if you decide to go down the obd1 route.

when replacing plugs just get the stock normal plugs, do not bother with platinum.. as for leads unless it is missing do not bother replacing them, just make sure they are tight on the plugs and tight on the dizzy cap.

You ITR ecu cannot be tuned for some technical reason. An obd1 ecu can be chipped and tuned.

ps, I have a conversion harness you will need if you need it.

if you only have tek it cant be changed as it isnt variable.

you will gain power by having it tuned but its not going to kill your engine if you dont.

up to you how much you want to spend on it, a crome chip tune and conversion harness will run you about 6-800, but im unsure who in wellington can tune it for you.

feel a little bit more power but from coupe r's dyno sheet seems like I should feel a bit more?

Thats because I had a crappy aftermarket crush bent 2 1/4 system on there, then went to madrel bent 2.5".

oh and just because one person got a good gain doesn't mean everyone will get a good gain, even though setups are very similar they still make different power levels

drive train loss is usually around 15%

hating on the subbys yet doesnt know about his own honda.... kidding mate haha,
after a tune expect around 130-140kw atw with a bunch more midrange power,
taking 15% away from 150kw (for arguments sake) you'd be left with around 125fwkw.
remember though that these were figures quoted when the motors were brand new...

yip to get that sort of power just look at a decent header and exhaust system and a basic intake preferably with cool air feeding it, plus the chip and tune you have mentioned and you'll be away. there are literally hundreds of examples on here to look at and compare

haha bloody subys ae, even tho my mates sti will anihilate most things on the street id take a dc2 any day, plus they are bastards to work on

yeah i got the bolt on's sorted just need a ecu/chip/tune then ill be away laughing LOL nah kidding i hope at least im suprised and proud of what a n/a can do

Just going to put it out there, probably best not to link to those videos here, We generally try to stay away from the whole street racing/drag train scene around here. Its not a good look for the club.
