Hey all... I'm sure anything I post has already been beaten to death, but the search server is down and I'm a complete n00b when it comes to FI.

My master plan:
After much searching and looking at archived posts until my eyes almost bled, I've decided on what I want to do and I think how I want to do it. I have a 97 D16Y8, bone stock with 100K. I want to piece together a setup that allows for 180-200whp at maybe 7 or 8 psi. I want to run this on the stock internals too.

EDIT: I've decided to go with Hondata. Read through...

Greddy e-manage would work too, just buy the one that does not come in the kit, and get it tuned.
I wouldn't recommend the vafc for fuel management.

you can get the software for it here, and talk to the suppot group.

also no need to goto obd1 with above.

 

For your goals you are better off going with an EIC, extra injector controller.

It is impossible to tune a VAFC for a turbo. It just is. Boost in not RPM dependant, but the fuel corrections with a VAFC (or basic eManage, etc) are RPM dependant. Thus it is simply impossible to tune the car for each and every situation.

There are several good EIC's out there, and some are less expensive than a VAFC. You could build or buy a MegaSquirt and use it as an EIC and boost controller if you wanted. Or there's the 034 ECU EIC.

But basically, what you would do would to put check valves to your stock MAP, so that it never reads boost, then use the EIC to inject additional fuel via 1 or 4 additional small injectors. With this setup, you maintain an entirely OEM fuel setup when not in boost, and don't have to alter the stock ECU or fuel system in any way (besides having to plumb lines for the extra injectors), so would have the best chance of passing emmissions while remaining OBDII.

 

If I read the last line... Opps.

You could run the SAFC, and get a MSD BTM, that isn't the safest but it will atleast get you around if you don't want to go OBD1.

There should be no need for check vlaves, when you run bigger injectors with the hack, and might as well just take a peep at megasquirt. That is a link to the forum^

 

In my experience there is more than one problem with the VAFC than just timing. Timing get jacked, accelleration correction gets jacked, but worst of all, the ECU calculates an entirely incorrect load for the engine, and tries to tune the AFR leaner because of it. If you use check valves, the ECU will at least read 100% load when you are in boost. It will try to inject more fuel to maintain its target AFR, but you will have to help it by adding the extra fuel yourself so your stock injectors don't go 100% duty.

 

nothing wrong with the afc i been using it for years...you can even wiring the map sensor to both map and throttle so you can make adjustments off map instead of throttle...most fuel adjustments i do off an aftermartket fuel pressure regulator...simple and effective fuel control...

How did you resolve the ignition advance problem associated with trimming larger injectors with AFC? Are you running OBD 2 or OBD 1?

 

I've decided to go with Hondata.

Can someone tell me if I can use a AVC-R with the wastegate on this turbo:

I'm really thinking of buying this, would this kit be a good starting point, or a big low quality rip off?

the avc-r does support the internal gate

to get everything you want in a turbokit, it has to be a custom kit

 

That's what I figured... I'm still looking, turns out that autochrome **** sucks anyways. I wouldn't buy it if people on H-T told me not to.
