turbo update/ forced induction

[sickyute]

i've been monitoring my car a lot lately...more than usual.

reason being i know how weather affects forced induction vehicles, specifically turbo vehicles...

the colder the weather, the leaner it runs, especially if it was tuned under warmer temps...

well...
there is absolutely no change in my AFR readings. None that i can detect.

it's gone from high 80s to low 80s.
from low 80s to low 70s
from mid 70s to low 60s

i just took it out for a spin and it was 57 outside... the AFR is the same as what is used to be when it was warmer out.

what gives? i have no clue.

but this is 100% good news...
reason being with a reflash u never know how weather would affect the tune. if it altered the tune when it was colder u'd be running leaner the colder it got...with a reflash u would not be able to compensate or retune so ur fun would pretty much be gone until temps got back to normal...else u'd be dangeroulsy lean ...

this is not the case i don't know if honda or hondata is to thank for that..

for those running comptech superchargers...do u see any difference? do u even have an AFR gauge? i think it would be a god investment seeing as we are all running on reflashes right now.

until some form of tuning software is available...we'll only have a hondata reflash...atleast i know i don't have to worry about retuning for weather.



just another heads up.

maybe it has something to do with the closed loop MAF sensor thingy system.

mainly i believe honda improved upon the barometric pressure compensation and intake air temp compensation as well which was an issue in the earlier ecu's. the z3 ecm displays this ability as you can see from Marvie's resluts. its been the same on the shop car as well. we are attempting to make it to the track in the next couple of days to take advantage of the denser air.

although the w/b should always be watched, a reflash can compensate for a/f when it gets colder outside. thats another +, especially when comparing a fuel computer/controller and an all out reflash.

okay first off 57 ain't cold.

I need to know if this kit can run in the winter. like can someone test it in like the 10s or 20s. I don't need it to act like a beast then, just run with out blowing up.

[F.I.A.T]

im pretty sure it will run the same. if you have ever been able to take a look at a honda compensation table you would see its accomodating for temperatures that all of their vehicles would be exposed to.

There are boosted cars in Pennsylvania right? So this wouldn't be any different. You should be good man, get it!!

from 87 to 57 is a drastic drop in temps...
and where it's not cold for you... it's cold for me... i come from a place that never sees temps below 80..
and now i'm in florida and it's not much different...

u say 10 is cold... tell that to someone in British Columbia or Alaska...i'm sure they'd say that's not cold.

I live in Georgia in the summers it gets up into the 90s and for the past week in the mornings it is 30-35 mid afternoon it is low 40s

Look up Winnipeg (more specifically) ...

It was 33 here last night. We had some flurries. I live in North Ga.

[TreeFrog]

i had freazing fog last night. it coats the car with frost a nice glaze, and you can't get it off for shit

so with this being said, what's to be said about turbo in places where it snows? I live in Kansas and we get 3-5 good snows a year with Winter regularly being in the 20-30's. How would this work for an SI with the AJP kit? Not recommended??

just remember...
where that is concerned...it's not about the AJP kit...it's about forced induction generally.

so far... it has gone against the norm already, which is good new and that's not because of the AJP kit...that's more than likely because of honda, ecm functions, maf/map readings, map compensations etc etc...

no one will really know how much more different it will be when the temperatures plummet. but it can't be bad...

where turbo is concerned....colder air is always good.. it will = higher efficiency of the turbo, more power, so on and so forth.... ur turbo stays cooler, oil and so on at better temperatures which = less stress on the motor and the turbo etc etc...

ofcourse extreme cold will have an adverse effect on anything including metals...rapid heating and cooling is never good for metals and so on...so as with everything else u have to take the proper precautions and so on...

chances are with snow on the ground....u won't be boosting anyway...so there should be no worries there....

u'll have a harder time stating ur car in colder weather...that's for sure...

someone else can shed more light...

PS: this is not only for the AJP kit but for forced induction/any turbo kit in general

i have one question, when u went turbo marvie. did u disable the vtec? sry for being ignorant on this subject =X

my vtec has always been 100% functional...
same goes for everything else in the car including the AC.

however vtec is now at 4200rpm and not 5800rpm..so it has a longer duration....all the way to 8600rpm..

o i c... people i know have always been telling me that you have to tune it perfectly when u go turbo otherwise it'll screw up or something...

[neyugncul]

good to know tho thanks! i plan on getting the AJP turbo kit.. most likely stage 2 around spring time.

with any major upgrade...turbo or supercharger or NA mods u have to make sure ur tune is up to par or else u will screw up something..

this is the reason AJP has a professional hondata tune available for the kit...so no worries there...

but that is a correct statement...u need to be closest to perfect as possible.

damn your frrrrockkkerrr... write a damn book or something... jeezz... yo did you get that ps3 yet or what??
