Look over my tune?
Look over my tune? Posted this in the tuning section also buy figured this section would be good also.
Could you guys look over this tune and let me know what you think?
First time tuning and i'm a little hesitant with the timing and boost with the higher compression from these heads.
Any feedback or tips would be awesome!!
Car is a 98 Camaro Running a 2 bar SD tune
Stock ls1 with rod bolts
Stage 2 Patriot heads
224/563 cam
ls6 intake with 60 lb deka
Single racetronix pump with hotwire kit
Front mount truck manifold kit
On3 76
Running 91 with a Progressive methanol kit on a size 7 nozzle

Looks pretty good. My suggestion is take the car to the track and see what it likes AFR and timing wise. Are you running 100% meth? Looks a little fat in boost and could use some timing in the lower boost area up to 5-6psi. Most run NA timing up to 5-6PSI.
Thanks for taking a look at this, i'm new to this and trying to learn as much as i can.
I'm running 50/50 meth with it set to come on at 2-3 psi and full on at 10-12 psi which it probably won't ever see.
The timing is the scariest thing for me, i'm not sure how to go about properly scaling the table or if there's a Histogram for that type of thing. I've heard things like you should take out 1 degree for every 2 psi or 1-1 but that seems like it would be too high seen as the N/A tune had 29-31 degrees where i'm only seeing 13 degrees, And i'm only seeing about 8 psi. I'd rather be safe and leave a little on the table.
I'm currently trying to lean out the AFR's a little, i've got the PE table set to 11.3 but it never gets that lean, i'm assuming the meth is the reason for this. I think i've got the VE table pretty good as it cruises pretty well but it gets a little tough trying to dial that in because it seems the car gets lean after it gets hot then screws up all the readings. I extended my IAT sensor and moved it down by the fuse box area and it seemed to help but i still get that sometimes. It does seem to help to get on it enough for the meth to activate and then the AFR's come back in line.
Also does all the injector data look correct? They are siemens deka 60lb.

Does the VE table affect WOT? I've been using the PE for WOT, i've mainly been using VE for driveability and cruise AFR's, i've been tuning the VE without the meth. Only time i was using meth was when i was getting after it pretty hard.

Verdad Gallardo I set my PE for desired AFR and then tune my VE to match said afr.
So anyone have any opinions or advice on where to go with my timing table?
If you still want help post up some logs and we can discuss.
I'm also new to tuning but from what I've read this seems to be a good way to go.
