PnP ZR-1 ECM - Raptor Skunk Works...

[VetteMed]

I'm about 6 hours from Atlanta, and my motor is pretty much stock other than exhaust... but I'd hate to lose use of the car for 3 months.

I live 3 hours away in Charlotte with catbacks (easy change) and nothing else. Wife would love to see the car gone for awhile. And my'75 needs some love!

Both Tod and I am having problems getting good driving manners with our packages. Mine 396 stage 2 cams extreme PnP, his 427 with even more exterme PnP and wilder cams. I know I would be interested in a plug in system with the software that is already avaiable for the unit. I am currently running dual wbo2 just to try and get the dirveability right. Woud not mind being a genny pig.

Tyler,the shop that build your motor why didn't they tune it?
This is why a camed LT5 needs to be left to the pros,not for DIYer's.

Also you say Stage II cams Stage II exhaust is too big still could be tuned to drive nice,drop it off, i'll take care of it.

I would have to agree... After all Pete had everyone eating his sausage in BG.

See what you started!

I'm not a stickler... just so it's not mean spirited! (Towards me that is!!)

Take the tune up with Corey. This motor is running no secondaries, agressive pnp, the first set of Jeal headers, one of the first sets of B&B with a xpipe and 36 in chambered exhaust pipes in lue of resonators, and full on injectors all the time, not something even pros have much expience with. Watched it with dual widebands yesterday and it is around 14.7 afrs most of the time in normal driving with one bank going slighly lean, its close but the main problem is the refusal to idle down when the clutch is put in until it comes to a stop. I think its in the iac steps as they show only 5 in the step down counts from 60 mph to 0 with the final step at 30. Hopefull I will get TunerPro set up on my non serial laptop tomorrow so I can watch what calibration cells are active. Finally got a decent *.adx file so I can link it to the actual *.bin the motor is running on. The *.xdf file is complete hack from the an ORIGINAL GM calibration document that I have had for a while. I give credit for the *.xdf hack to Tod P who had most of it done when I sent him the document. He also did the *.ads file which has been converted to *.adx to work with the most recient version of TunerPro. I ain't no pro but I been around long enough (1997) to know what works.

PS I have one of the first MegaSquirts so know quite a bit about that too.
