scutch0 Posted September 22, 2006 Share Posted September 22, 2006 ok guys, while im soring my new V with some alloys and other bits and pieces, what do you guys recommend for some initial tuning mods?ive got my hks super bov fitted, and i am probably going to stay with the boxed airfilter (getting a blitz panel), i have a backbox waiting to go on also, but im just wondering what would be some good choice modifications to start my power hike before i start going down the fmic route, i'd like to get one of the blitz ecu's but i know theyre as rare as rocking horse poo. what do you guys suggest? i will probably get the exhaust system rebuilt just after i fit the backbox, is 2 1/2" bore ok?also, why is it when i tryed my apexi airfilter on it the other day it went down in boost slightly? as in, it runs more boost with the standard airfilter in!!Rich.

Sparky Posted September 22, 2006 Share Posted September 22, 2006 Decat would be one of the first mods and a FCD ;) Then sort the fuelling out, uprated pump etc Link to post Share on other sites
scutch0 Posted September 22, 2006 Author Share Posted September 22, 2006 is there a way around going down the fcd route? would one of the blitz tuned ecu's have a higher fuel cut? Link to post Share on other sites
Sparky Posted September 22, 2006 Share Posted September 22, 2006 I suppose if you dont want to go down that route you would need a mappable ecu to set the fuel cut to whatever boost you want ;) I take it the Blitz is mappable Link to post Share on other sites
NDR008 Posted September 22, 2006 Share Posted September 22, 2006 a) don't go down the fcd route, if you don't simultaneously fit an uprated fuel pressure regulator. i've seen many people lean out because of this.;) fmic is the best and most basic mod for all future modding - i'd save up for that first of all, that is the best basis for anything.c) scrap that panel filter, and do something that can take in more COLD air easily.d) decat + better exhaust flow.Oh and a blitz ecu - you wont be sure what it was tuned for, and might not suit your near stock car + even more of a reason to use a fmic in my opinion - to play it safe.

miracle411 Posted September 23, 2006 Share Posted September 23, 2006 I like the way this guys thinks! Thats helped me out aswell there mate, cheers. Link to post Share on other sites
ecksjay Posted September 23, 2006 Share Posted September 23, 2006 the full exhaust is the first thing you wanna sort, just a backbox on the stock system wont do shit. you wanna aim for 2.5" bore all the way through if you can, coupled with a decat as mentioned above.a mani would be a good bet also, wepr/roadrunner/jam etc, but with those three you'll prob be very close to fuel cut then (i'm just under fuel cut now with only exhaust, standard cat and standard mani) which is when you wanna look into managemen/fuelling mods.an aftermarket ecu like a blitz or a jam will remove fuel cut altogether, not just raise it, they will also remove all the other limiters and possibly increase the rev limit slightly but it depends what it was originally mapped for.luckily i know what mods the blitz ecu i've bought was mapped for so i can aim for that, if not then i'm hoping it'll run fine on a lower setup, at most it'll run rich which could prob be knocked back with an afc/reg etc.if you need a chat mate then give me a shout.

scutch0 Posted September 23, 2006 Author Share Posted September 23, 2006 cheers eks, thats really helpful. ;)i dont want to get a decat until ive got the fuelcut sorted... as ive limited on money at the mo, so i dont wanna drive around right on top of fuelcut as i wont have the money to sort it. how much do the blitz ecu's go for?does anyone know of someone who could source me one?and if its mapped for a totally different setup, will it not compensate the fueling anyway? so it would be fairly safe?NDR008, do you not loose some boost when you fit a fmic? as i dont want to go down the route of a bleed valve to increase the boost if it drops...any other recommendations?Rich.

NDR008 Posted September 23, 2006 Share Posted September 23, 2006 yeah, but getting a decat and better cold air intake will help the car boost faster (and possibly higher) without bleed valves and stuff like that.Also though a fmic supposedly drops boost due to the higher volume and distance air has to travel. The quality of the charged air - being cooler (not absorbing heat as much from the engine as with a tmic), will give you more affective boost.oh and for setting boost - get an HKS actuator. ;) Link to post Share on other sites
Ryno Posted September 23, 2006 Share Posted September 23, 2006 before you think about going faster, can you stop well?, can you take corners fast?should always up-grade brakes and handling before thinking of going faster, for obvious reasons!when thats sorted, full de-cat system, bored gastegate......then save to get things done propperly, fmic, manifold, bigger turbo, relocate air filter, power FC..etc ;) Link to post Share on other sites

ecksjay Posted September 26, 2006 Share Posted September 26, 2006 well, i've already been offered £450 for mine. I know of a jam ecu which is up for sale at the moment but i've a feeling its gonna go for close to that too, if not more.braking wise, ye i need mine sorted also, fades far too easily. abs is on all the chuffing time !
