FSCM and ECM tables should match?
I am going over my tune and there are a few redundant tables between the ECM and FPCM in a 2016 Camaro SS. Should these tables match each other completely? Including axis information? The tables I'm referencing are ECM 6976 regulation pressure and fscm 6995, and ECM 6975 max desired pressure and fscm 6994. My ECM 6975 axis starts at 0 and ends at 56.0 g/s. My fscm 6994 axis starts at 0 and ends at 48 g/s. and the pressure starts at 560kPa and ends at 586 kPa.

My regulation pressure in ECM 6976 starts at 450 kPa and ends at 586 kPa with axis 0- 56 g/s
fscm 6995 starts at 450 kPa and ends at 586 kPa with axis 0- 48 g/s


Are these tables supposed to match each other in both pressures and axis values? I have an aux fuel pump and I'm wondering if these tables not matching completely could cause issues.

Hey, didn't see your post until today. Sometimes the boards are weird about sending me notifications. Yes, as far as I can tell, the tables should match and have the same axis. Mine do. In fact... I also had some issues with the aux pump when they did NOT match.

next wow or mm is july. Need to get another run in to, hopefully, erase the 11.5 in my sig with something better.

Here's the screenshots you requested via PM. Can't say it will work for you, just what I have

Looking at doing a procharger on my “Lt1 trim” car when it comes in next month. Thanks for updating this post! On thing I’d say you could use is a dragy. Track isn’t always open but the streets are ��

Thanks! Actually i did just get a dragy a week or two ago, but i need to upgrade rear tires before it can be useful. Still breaking traction frequently under power, hard to get a good read on it. Plus i live in the Missouri hills. An actual long flat road is hard to come by.

Going to be ordering some DRs very soon here.

I'm having a heck of a time finding drag radials in 305/30/20. Ordered some from Summit over a month ago, but they are backordered, and the delivery keeps getting pushed out.

I looked at getting something in 17" dia, which has more tire availability but then id have some mismatched wheels/tires front to back in terms of tire sidewall, and even just wheel looks since racestar has discontinued the wheel style i bought.

Soooooo..... i may be going to the track on the NT05s again, and just trying to launch in 2nd. Unless someone has some leads on DRs.

I still have the original wheels, so I also considered replacing the 275/35/20 original tires with DRs but availability is limited there too.

Seems like everything in 20s is very limited.

How is the quality of Forgestar wheels? They have wheels in 17x10 that are supposedly flow formed (i assume not true forged). They tout lighter weight, but i couldnt find weight specs on their site, which makes me suspicious. Plus they are pretty cheap in terms of cost. I really dont want to spend $1500 on Welds although thatd prob look nice, lol.

I’ve got the Forgestar D5 Beadlocks in the rear and standard D5 up front for skinnies. Seem like nice wheels.

Dragracingwheels.com provides a lot of specifications for many wheel manufacturers. Also, if you sign-up for their newsletter, they are continuously offering discount codes. Delivery and customer service was good.

Nitto 555Rii 305/35/20 and 275/35/20 are on eBay right now.

I have the 305 35 20s, mines lowered so they tuck right inside the fender well lip perfectly on the 20x9.5 Carbon Flash wheels.

Finally got some DRs. Now just need to find some fronts that match.

Considered both the 305/30/20 (never in stock) and 305/35/20 (dia not compat with fronts for .... computer reasons).

Ultimately went with some 17x10 ForgeStars and 305/45/17 NT555R2.

Absolutely no regrets there. They look badass compared to the 20s. Love the meat in the back. Not going back to 20's in back... probably ever... although I still have the original 20's and now some RaceStar 20's for.... I dunno... double-backup? Anyone want to buy some wheels?

I wish I had a scale to measure the 305/30/20 NT05s on the RaceStars compared to the 305/45/17s on ForgeStars. By feel though... the 17" combo has to be 10 to 20 lbs lighter per wheel/tire. It's a VERY noticeable difference.

Traction-wise it's great, although I still can't do a WOT 1st gear launch on the street. No place to really do a proper burnout and launch around here. Without burnout and launch in 1st they start to hook a bit, but as soon the RPMs come up a little and boost kicks in, they break loose middle to top of 1st gear. So I think 2nd gear launches on the street are good to go, and I'm pretty confident I'll be able to do a WOT 1st gear launch on a prepped track w/ burnout.

Ignore the dirt, but here's some pics. I've got no reason not to get to the track now.

There are 3 more races at Gateway so you better get back out there or change the title to something else. Come on out on the 15th, I'll be there running the VP heads up so lets see some results after all your hard work and tuning etc you've done. Bring those 555 r2s to the track, do the burnout and lets see if it will hook. I have confidence you'll finally go fast. Right?

No pressure at all! I’m still following this thread and hope you make it back out there soon. You’re going to do better with this setup.
