why cant i boost in 1st gear?
 

hey everyone, as some may know ive been working on my turbo(install), but i have a prob with boost in 1st gear. when at idle my vac is around 20(vac) and when im in first the gauge go's to about zero(boost/vac) but as soon as i shift to 2nd i have boost. this is what i have(if it helps) dohc zc t-25 turbo a chipped ecu(te) dsm blue tops and a 2nd gen bov. the bad part is im still using a 4spd tranny and as of know i dont have an intercooler. so why cant i boost in 1st?? thanks for any help

Re:why cant i boost in 1st gear?
 

What kind of boost controller are you using?

Re:why cant i boost in 1st gear?
 

as far as boost control i have my ecu chipped by xenocron(set @8psi) do i need another sort of boost control?

Re:why cant i boost in 1st gear?
 

just being curious are you useing a fpr or and fmu by any chance?

Re:why cant i boost in 1st gear?
 

yeah i have a b&m fpr and the b&m gauge reads 35-40(wot) psi if that matters/helps

Re:why cant i boost in 1st gear?
 

I don't boost much in 1st either and I just assumed that there isn't enough load to build boost

Re:why cant i boost in 1st gear?
 

Most likely has to do with your tuning. What ECU program did you use for engine management? I would ask the person who burnt your chip what they did to the settings for first gear. Its a good thing that you dont boost much in 1st anyways to avoid blowing your motor in that short gear span. First only gets you to like 35mph anyways.

Re:why cant i boost in 1st gear?
 

i have a chip from xencron and its in my pr4 ecu. and i need to boost in 1st because right now im rockin a 4speed

Re:why cant i boost in 1st gear?
 

For at least ODB0 ECUs, the ECU has no idea nor does it care what gear you are in.

Re:why cant i boost in 1st gear?
 

does that mean you can boost in reverse?? :P

Re:why cant i boost in 1st gear?
 

Sure you could, the ECU doesn't know or care nor is it able to control it even if it did.

Now, let me know when you plan on boosting in reverse so that I can make sure to clear out of the way.

talk about scary :o

Re:why cant i boost in 1st gear?
 

this happens to mee too..i cant seem to get past 4-5psi, WOT in first. now my buddy with a SR20DET can make like 10+ just by chucking revs at idle

Re:why cant i boost in 1st gear?
 

tiny turbo on a bigger motor

Re:why cant i boost in 1st gear?
 

I can make 15psi by chuckin the revs in idle ;D

On another note do you really have a reason to boost in first gear on a front wheel driven car? Isn't lighting the tires up easy enough in second gear?

Re:why cant i boost in 1st gear?
 

this guy has an Automatic not 5spd, automatic will shift on it own u cant control shifting in automatic, unless u go like 15mph and then give it full throttle. i had an automatic, and that ---- sucks, switch to 5spd and you'll see a world of a difference

Re:why cant i boost in 1st gear?
 

are you sure he has an automatic and not the civic std 4spd manuel tranny?

Re:why cant i boost in 1st gear?
 

get a manual transmission, automatics undershift in first-not enough exhaust pushing the turbine.

Re:why cant i boost in 1st gear?
 

yeah it's most likely the 4 speed manual since the auto tranny wouldn't have lasted long enough for him to make this thread

Re:why cant i boost in 1st gear?
 

yeah i got the tranny the never quits :-\ manual

Re:why cant i boost in 1st gear?
 

his t28 is way bigger than my 14b, and i have more displacement than he does..only thing he has is the DOHC.

Re:why cant i boost in 1st gear?
 

Where are you coming up with stuff? Did someone actually tell you this?

100% wrong on both points.

Re:why cant i boost in 1st gear?
 

hmm thats weird then.....is he running smaller stock IC pipes compared to what your running?

Re:why cant i boost in 1st gear?
 

Well the tuning point was just a theory...the 1st gear thing was me thinking about a problem a fiend of mine is having with boost spike. I forget that not everybody has that. :-\

Re:why cant i boost in 1st gear?
 

i was thinking the same thing, everytime i'm in uber, it doesn't have settings for every gear.

lol

where's hotrex to bach this no0b

Re:why cant i boost in 1st gear?
 

'

nope..im running 2" everywhere except for where i used my old CAI. and he has 2.5" all around.

its not a big deal. i just cant figure out why.

Re:why cant i boost in 1st gear?
 

u guys are tards =x most cars can't produce enough load in 1st, mine creates full load and breaks traction from jus flooring it in 1st. depends on what size turbo on what motor. u guys come up with the funniest answers ive ever seen...

Re:why cant i boost in 1st gear?
 

What version of Uber are you using? I saw some setting about gears in the newest version...not really sure what it was. I was just in the car watching my buds car get tuned.

Dont be an asshat either guy. I dont see you trying to help him ::)

Re:why cant i boost in 1st gear?
 

i build about 8psi in first

Re:why cant i boost in 1st gear?
 

like turboda6 said.
it`s prob.ly just the size of the turbo.
(what`s the size of the turbo? i didn`t read the whole post :P)
mine don`t see boost in 1st and it wouldn`t hit full boost in second.

Re:why cant i boost in 1st gear?
 

i don`t have the newest verison but are you talking about the shift light???

Re:why cant i boost in 1st gear?
 

A big boost spike in first gear wouldn't matter at all because the gear is over in like one second. Besides if you have to be worried about a few psi then you have a shitty setup.

Re:why cant i boost in 1st gear?
 

:(

good thing it takes less than a second to break something. boost spikes in 1st is not ok lol

i built full boost in tire fryin first gear

Re:why cant i boost in 1st gear?
 

considering i have all three versions (1.66, 1.78, and 1.8) and i've never seen anything about specific fuel settings or boost settings in each gear. how long would it take to tune it if it was like that?

i'm helping this guy by making sure he doesn't listen to what you're telling him to do :P

Re:why cant i boost in 1st gear?
 

hey thanks for all this help that you guys are givin ;D again i have a 4spd manual tranny dohc zc with t-25 turbo and turbo edit. so i dont think my setup is shitty it's just that i have a 4-speed so all the boost counts(i have an si trannythat i want to swap but im unable to) and now that ive been drive'n the car more.... sometimes it boost in first, but most the time it wont (bout a 6:1 ratio) so that is why im somewhat concerned. thanks again

Re:why cant i boost in 1st gear?
 

I dont make boost in first...I might make 1-2psi...no biggie...I have 2nd and 3rd and 4th and 5th ;D

Re:why cant i boost in 1st gear?
 

thats cuz ur turbo is the size of my head... u dont get full boost til like 3rd or forth huh?

Re:why cant i boost in 1st gear?
 

i have never heard of that problem before...i hit a easi 15+ psi on first gear, without hitting redline, or revlimiter.

???

Re:why cant i boost in 1st gear?
 

thats cuz ur turbo is the size of my head... u dont get full boost til like 3rd or forth huh?
well i never run to full boost(except a few times but i can hit full boost in 2nd,3rd,and 4th)

Re:why cant i boost in 1st gear?
 

Read what I said, if you have to worry about a little boost spike for a short period then your setup is ----.
