whattup guys

i recently installed the drag gen IV kit on my h23 prelude si.. its been running very well as of late, and since i'm in chicago, the temps have really dropped down.. during the night we see temps of around 20deg f. the car pulls very nice up to around 4K, but after 4K the car doesnt want to rev anymore.. its really slow to pull up the rest of the rev band..basically like i dont have any turbo at all..?? any suggestions/?

hmmm...my car only got stronger with the cooler air...however it did start to detonate because of the denser air

 

Yeah, I would think it would make it faster.

Same here

Hmm, just the opposite for me here and it's 0 deg F right now.

 

ben- what were you AFRs past 4k in the warmer weather? What temp was it tuned at?

totally untuned just bolt on boost. weird, its very strong up to 4K but nothing afterwards.. maybe a case of just having to get a nice tune


i'll make a vid of it maybe tonite. (its pretty cold)

what do you have for fuel and timing management? you shouldn't even be boosting if you don't have any management/tuning. That drag fmu is crap.

 

Get the ****** tune before the gay *** FMU break something...I got my car tuned in about 35-40 degree weather at 11.8-12.2. So once 80 degree weather hit maybe ill hit the 11.4 range. Hope im safe *it cant blow again*

Maybe
-- Its too cold for VTEC to engage?
-- You're low on oil and VTEC won't engage? (eeeek!)

Edit DERP! Non-VTEC...

Tune it you untuned bastard!

H23 is a non vtec engine.. haha...

Maybe your running extremly lean up top now? Or...
Check all vacumme hoses for leaks and Charge pipes and PRE turbo exhaust leaks.

Well that explains the no-power over 4000 RPM! (runs and hides)

is it better to tune in cold weather or warm weather? seems like people who have done their tuning in warm weather have higher or lower afr in cold weather

 

if you tune in warm weather and dont leave room for error. In cold weather you will run leaner prolly and cause problems. So if your tune is conservative you should be ok. Or if your running Uberdata... Tune a warm weather chip and a cold weather chip i guess

 

im out here in chicago too its been getting damn cold, see i dont have that problem my problem is it doesnt want to start in the cold, i have to hold the gas down a little bit for about a min than it will idle fine, but the colder it has been the car runs stronger

**shakes fist** damn you! lol...

too broke to tune.. and also what type of tuning is even possible with this setup! it uses fmu and an inline pump! lol

I would sell the inline pump and fmu and start saving for at the least a hondata, 255 in-tank pump, and better fuel injectors.. It may take some time, but at least your engine won't be detonated.
