Crome lauch control

[b18c1]

was looking at pgmfi.org and reading into crome's launch control any one had issues with it? and is there any one in auckland that can add this to my chip? as i wouldn't mind giving it ago, i know coupe-r tunes with crome but hes all the way in tga and its a bit far from home. cheers guys

[d16a7]

couple of locals can write chips...

and the launch control is quite fun.. i miss mine.. got taken off when car got tuned.. forgot to ask to put it on again.. it also has full throttle gear change feature too

[Horny_Devil]

tianporn should be able to do it for you as i believe he has all the gear

[Coupe-R]

if your car is chipped and tuned with crome this feature can EASILY be added.

can do full boost launch but requires A LOT more playing around to build boost perfectly.

or you can be all gangstar and make your N.A honda shoot flames on the launch for ignition retard (ment for boost building )

yip its already on crome but i didn't realise that it had launch control till after i had it tuned etc bugger
its n/a so i won't be boosting
hmm last option sounds cool but wouldn't that be bad for my car?

so tianporn should be able to help aye, i'll give him a pm,but on another note what would be a good rpm to launch at? i've played around (with out launch control) with different rpms from 3000-4500 and i just get the mad wheel spin, what do ya reckon?

[Green Machine]

1500 so you can launch from traffic lights!! nah around 4-6k Id say. You dont want it too low incase the track is really good on the day and you could get grip higher.

[b18c1]

yeah good point i'd prob go for 4500 then, i will try it out and see how goes,

[b18c1]

does any one know of tianporns cell number? so i can give him a call? pm it through if ya do, cheers

[Horny_Devil]

just pm him if ur in no hurry

I never use launch control in crome using the speed sensor method.

that means when ever the car is stationary it will hit a lower revlimter of what ever you want (say 6k)

but what if the track is sticky, what if you change tyres etc etc.

I don't beleive in them, just use your foot

Now building boost on the line, thats effective

yeah i don't mind the stationary revlimit at all, and ive never been onthe strip before either, but getting the limiter on there means i can play around with it and try new things which is what i like to do.

no getting the limiter on there means you can't play around with anything.

it will mean if you want a set limit of 6000rpm for launch control.
that is static and the value is burnt to a chip.

if you are at the strip and find 6k is not enough you are stuffed. (you cannot control it with the turn of a dial, it is written to the actual chip inside the ecu)

Actually there maybe a way to activate launch control with the push of a button like the A/C swtich BUT it will still only be set at the static rpm you set before burning the chip

[ef_eg]

Crome launch control is basically useless in its current form. Being stuck to the fixed limit is a waste of time. Systems like gizzmo launch control are much better because they can be adjusted at the track; and you can rig them up to easily disable it while stationary for your burnouts.

[Coupe-R]

Crome gold, you can have it turned off for burnouts etc,

you could do this with crome it would just take some setting up.

Only advantage of revlimit launch control is for building boost.

Otherwise for N.A just feel what the track is doing and go for it

[OhSoSlow]

Coupe-R Do you think it's doable to have crome launch control set up off A/C switch? Would be a cool feature, for wank factor if nothing else..

[Coupe-R]

hmmm possibly, i havn't looked into it.

maybe ask on pgmfi forums or search around on there

[b18c1]

yeah that would be mint, at the flick of a switch your launch is set, kool, s who has crome gold?

[Coupe-R]

me, locust 2000, python few others i guess.

Anyone who has actually paid for crome can use crome gold

P.S if you have a crome tuned car not on gold, it would need a quick retune as they are quite different.
I.E injector pulse is slightly different even when using the same raw value in the map.

Ask questions on pgmfi.org for launch control activation

[d16a7]

whats always bugged me is how the hell crome knows what gear its in? does it take a guess by load or something? the features on crome gold look mean! with the antil lag and all that jazz..do you need crome pro to run a gold map or something.. i just tried with 1.5.0 to open the default gold map.. and nothing happened came up with error saying invalid file.. meh was looking forward to just having a play around and seeing what happens.. *edit* just re read your post.. looks like i need pro.. lol oh damn.. wanted to have a looksy and play..

[Coupe-R]

do you need crome pro to run a gold map or something

yes

for gear it takes the RPM of the motor and looks at the vehicle speed then works out what gear you MUST be in.

I.E 3000rpm at 25kph you must be in 1st etc

if you change gearboxes you can setup the gear tables differently

hondas don't work out "load" as such, just manifold pressure.

Air flow meter cars work out "load"

[racerdad1]

sorry to but in just saw this and thought i might put my few Cs in... i launch mine at 3000 and onley get a lil bit of spin and then vtec kicks in so its all good lol

[Coupe-R]

uhhhh I launch mine at 6000-7000 and get some wheel spin with hoosiers.


It's only good for building boost, the track can be different each time so you need to change your launch RPM each time. Not hard to hold your foot where it needs to be
