View Full Version : Tough VA emissions - need help

time has come for VA emission again

the standards are very tough, the LSV is a 390 ci, full porting, big valves, and has the 234 cams which make it very tough

I also have the secondaries removed which reduces the "port velocity" swirl, runs off both injectors above 1% throttle

the 48 HC standard typically gets me, I'm well over it, usually around 130-150!!

I'm considering brand new cats on the car as mine are the random cats and several years old and from what I understand don't do that great a job (great flow though!!)



I'm looking to potentially get an emissions chip burned, one person even suggested a chip for M85, but I've never seen that done.

anyone pass this tough a standard with a stroker ZR-1?? don't think it's possible but any alternatives (short of moving or selling the car :cry: ) are welcome


anyone have any suggestions??? I'm coming up due in July



thanks!

Ron,
I have a stock 94 chip you can borrow if you think that will help.
Might think about unpluging all of the secondary injectectors so you run just on the primaries.

not sure the big doggie would even run on a stock chip. but it might be worth a try

thanks Pete, chicago is a bit of a commute for me!

I forgot to mention before...
My car has a Doug Rippie chip in it and it passes just fine with it in place. I have the stock chip but have never installed it. The engine is very close to stock so that probably explains a lot.

Let me know if you need help. I'm in Anaheim so I'm close by.

I feel your pain. I have a post running on the very topic, but here in Ca.

It sounds like you have a pretty hard HC limit to hit. How is the test done in Va? Is it on a "Dyno" or just in neutral at certain RPMs?

on a dyno at idle 15 mph, and 25 mph

need to find some help as with this configuration I don't think I have a prayer of hitting 48 HC unless the car is tuned for E85 or something very special

an emissions chip and fresh cats might do it, but with these cams, I doubt it.

I finally passed today, but just barely. I hit 76 on my HC and the limit was 77. NO went fine this time so finally I am good. 48 sounds hard! :mad:
