Hesitation...Not the same kind

[MazdaSpeeder00]

Well now that ive personally fixed my IC connections and built up the nerve to get on my car every now and then Ive begun to notice a hesitation. This isnt the normal one that everyone talks about. My car didnt do this until the kit. but here goes

1. Im in first gear and punch it....my car goes but seems like its fighting a 100mph wind.
2. The turbo kicks in my car Hesitates HORRIBLY for a second and then the car takes off hauling ass as usual.
3. If im cruising along at 3-4rpms and get on it the cars seems weaker than usual.

So im at a loss. I did recieve a new PCM/ECU in the whole Mazda ordeal last week. DO you think that it needs flashed? they said it was, and i sure as hell dont think that this is the same hesitation. I hope someone has the answer

could this possibly be because of your bov venting air that the MAF is accounting for which makes the fuel mixture a tad bit richer right after a blow off. Which would im sure cause maybe a slight bit of hesitation or lack of power for a second until the extra fuel is burned away. I dunno just a thought

oh yeah also wanted to know how you like the wagner kit. I cant wait for mine to come. also hows the bov sound?

The bov sounds sweet.. Im not sure about the kit right now. Once i figure out these little odds and ends im sure i will love it.

Is there anything i can do about the bov and mixture?

well that pretty much happens when running any bov on our cars. Thats why alot of people dont want to put a bov on our cars b/c of the overly rich fuel mixture. Do some searches there are tons of threads on running bov's and dual bov and bpv setups.

I'm having similar problems with my car, and it's stock. Do you think it needs to be reflashed?

I was also having a weird hestitation the other day similiar to what you described. It seems like a really hard head wind and then it goes away. I though personally it was the wind, but it was calm out and it still happened. It's more like low throttle hestitation and goes away when you give it more gas

i don't kow why you guys are having problems with the hesitation i allready flashed my car and is working nice no problems.

I know its related to my BOV. But i dont have the means or know how to be switching it around. Maybe i should invest in an aftermarket computer then ey? SO this hesitation isnt gonna hurt anything then?
