car falls flat on its *** when I hit boost, otherwise its fine.
Just got the car on the road last week, and I have been taking it easy on the new setup. + I had a wiring problem with the secondarys but thats fixed now.
anyways, the car WILL NOT boost, it just will not happen. If I run it up in RPM and keep it near 0 Hg/in I can hear the turbo spin up, and the BOV goes off on throttle close.
As soon as I make about 2 psi of boost, the car just seams to hit a wall. No power, no boost and the exhaust sounds weird, like the car is hitting a rev limiter.
Im going to run a datalog tommorow and try and get some answers, and Im going to a Rx7 meet and hopefully somebody there can help me.
I am totally lost at the moment though.
I know its not the secondary wire that I fixed, because before I fixed it, I hit boost by accident and it felt totally different.
anyways, if you have any ideas...

where do you have your staging point? mine is around 2 psi... i was thinking that maybe you have your injection tuned wayyyyy too rich right after the switchover, you tried messing with the fuel? do you have a wideband?
also, what kind of secondaries are you running?

Dude, trying to adjust (fuel) maps without an EGT or wide-band is like shooting arrows in the dark.
I wouldn't even try to give you recommendations either way.
Since you're getting into the boost zones, there's a chance you could hurt your engine going the wrong direction.
Hell, get a narrow-band AFR gauge on the damn car will help in your case.

I have only touched boost, Im not trying to really haul some *** right now.
Anyways, im just going to drive the car without boosting untill I get it tuned in the spring. I might get a chance to use my university's dyno, and they have extensive exhaust analizing equipement.

well, I was looking at my maps on my laptop.
on the changeover it goes from around 7 millisecond durration on just the primaries to a 3.50
this is a instant %100 increase in fuel with the 1680 secondarys
7 at 550cc to 3.5 at 2230cc, this seams like a huge jump to me

Try moving the staging bar up to around 5 psi and see if it starts to pull up to 5 pounds. If it hits 5 and falls on it's face, you probably have way too much fuel at the crossover. YOu really do need a lambda meter or some type of metering device.
P.S. Make sure the correction maps are zeroed out from the hit man. I used his base maps and still grenaded a motor eventhough it was tuned perfect on the dyno. Most notably are the air temp maps!!!!!

kiddies work it out - 550 cc injectors, 7ms.
turn on the secondaries you have 2410cc
2410/550 = 4.3 so 7ms/4.3 = 1.6ms - so after the staging point go to 1.6ms....now that wasnt too hard was it?
Give more to be safe ha !

I guess 10 posts is the magic number, huh?
Yeah, I guess we'll all just follow Mr. average Joe off the streets comments on tuning high performance rotaries.
Add that this bitch can't understand English very well.
Wow, maybe you might want to try some Chinese Haltech Tuning forum?
They might understand you there...

im sure these other guys have big motors, that green buggy has a big motor for sure,
it looks great, however, i know you have a honda civic with neons......

You come in here claiming to have knowledge more than most of us, and then you go about blasting people in here?
Who are you?
Why are you hiding behind some screen name?
There's a stigma behind people who don't want to reveal themselves yet claim they are some expert...
Wow, if you know what I drive, you must be super smart!
You must have the gift that you can see my ride through the computer.
You scare me.

what do you mean about zeroing the correction maps
