max mods befor tuning NEEDED??

[norm84]

how you going peeps, just wondering what the maximum mods you can do (bolt on wise) iv a got a b16 in a eg,

this might be a stupid Q, for some. but i really want to know.

for the past cars iv had, (turbo) i didint need to tune it after changing the turbo and so on.. also as all of you know. alot of turbo cars if not all, you can just wind the boost up with out adding a piggy back or anything for fuel, and if you wanted to add a lil more fuel, you could just upgrade the fuel pump and get a regulator.


is it the same for these high revving NAs

and yhe its obvious, for maximum results you would tune it..

Upgrading the fuel pump won't deliver more fuel into the car, it only allows the flow of fuel to be greater if need be.

The ECU governs how much fuel to inject into the motor via input of various sensors such as throttle position, map/maf, o2, etc.

Too much fuel pressure can kill injectors. I'd look into a retune with larger injectors if you are over 90% duty cycle, fuel pump IF needed and an adjustable FPR. This way you can control everything.

For the normal bolt ons of intake, header and exhaust, you don't need to tune it. You can get a bit of extra after tuning though.

For NA, you also can't slap a turbo on and expect it to work because NA Hondas would normally have a low pressure MAP sensor. It won't give a proper reading when you go above atmospheric pressure by a substantial amount, plus the ECU is not programmed to handle a reading that is much higher than atmospheric, causing the ignition and fuel maps not to compensate for the extra air. Then, you have the stock injectors which are sized for NA applications and doesn't usually have much capacity left at a reasonable injector duty when you go for high boost pressure.

for bolt ons i meant, bigger TB and manifold.
once again, on my other cars i pushed out 200+rwkw on standard injectors. all it did was run a lil rich.

im not saying i want to boost it, so the power increase should still be right for the injectors.

You should be fine as long as you don't run ITB's/get big cams.

Unless you're opening it up and changing internals there isn't a "need" to have it tuned.

very true...

but just my 2c, if u want to get the best power for your mods computer is the key to this

mate with dc2r IHE went from 114 to 125kw atw with an ecu and dyno tune (neptune):thumbsup:

[TheSaint]

if you are just doing intake/header/exhaust you can probably get away with a apexi vafc2/apexi neo tune + dyno - should squeeze a bit more joos out of it and smooth out the power a bit

if you change cams or get ITB's than a desent ECU like hondata would be a good move
