heres my delima... i went awd in my ek, obviously using a crv trans, which is really like an h/f tranny... so in order to get the trans to shift smoothly from 1-2 i need to shift at around 7k, every other gear is great at 9k... so my question is what can i do to load the turbo to get the boost to "spike"... i am running a zenocron boost solenoid 13lb wastegate spring and s300... gsr block, b16 head, itr cams, top mount, precision 6031 with a .63 housing, tial wastegate, 750cc injectors, water/meth... made 440whp/285trq... is there anything i can do to the boost controller settings in the s300 to basically trick the system to spike up... obviously the s300 would protect it from overboosting and i have no issues with traction on street tires... these are all conditions at the track i am wanting to address... i am just trying to compensate for the short 1-2 shift that is throwing my rpm's at around 4500 at the bottom of second gear... the car freaking rips when it hits 10psi, i run it to 19.5psi and it spools fast, just not in that small rpm range going to second...

 

It's not going to boost much in 1st gear because not much load really, but in your boost by gear put it at 100% duty cycle in 1st gear and that will help spool the turbo by keeping wg closed

 

Nitrous

 

Im selling a DRAG manifold

 

You can't put it at 100% in hondata 99% is as high as you can go... With an awd car there is more load smanager 2.1 beta has quick spool, set it at 2 psi below desired boost level and viola you have your "spike" if you don't want it to work in whatever gear for whatever reason set it 2psi below you activation pressure.... Good luck

 

I dont understand how setting 2 psi below what I want will spike the boost... could you elaborate or show me a screen shot of what you are talking about... thanks...

 

What your saying is that your falling out of boost when you hit 2nd gear because you have to short shift 1st to 2nd. Unfortunatly this is more of a mechanical issue, you are experiencing lag in the lower rpm's of 2nd gear.

There is some things that could be done to the tune to help spool up in this spot, but it wont totally cure your lag, as lag is purely a lack of exhaust flow.

What exactly does the tranny do if you rev it higher than 7k rpm in first? I think the proper cure is to figure out what must be done in order to rev it higher than 7k rpm in first and keep your tranny happy at the same time.

 

its a common problem... i have sent it to synchrotech and let them go through it, new carbon synchros, friction dampers and an entire 1-2 gear set from honda... when i rev it past 7k it is a very hard shift, like it just doesnt want to go into gear and this delay just lets the rpms fall further than a quick shift to 2nd... i want to play around with full throttle shifts, but i need to adjust my clutch switch a little... you cannot have your foot on the clutch at all because it is so sensitive... i wondering if there is anyway to play with antilag while its in this FTS mode??? any thoughts???

 

you wont be able to do anything with anti lag, however you are thinking along the proper lines, full throttle shift and re tuning that portion of the map will result in better responce to spool up.

anti lag loads the motor up with fuel and retards timing to build boost while no load is present, so making adjustment to the map in a similar fashion could help, but youhave to be very careful how far you take it, anti lag is used in a no load situation, what your trying to do is under load, so drastic map changes could result in damage.

Another thing that would aid in earlier spool up would be ditching the top mount manifold.
A mini ram would help you spool a hell of a lot faster, and is still capable of providing enough flow for 440 whp.

 

this car is 10lbs of **** in a 5lb bag, lol... changing the manifold is not an option... i built it to work around the a/c ...

 

The quick spool sets the pwm to 99% until it reaches the the amount of pressure you set it at. after that it goes back down to whatever duty cycle % you have it at in each gear.

 

Does anybody use quick spool with boost by gear? It seems like its either/or.

 

you could install some sorta injector to shoot fuel into your manifold =/

 

The simple answer is Nitrous, just a small dry shot using your injectors for additional fuel.
