Best Bin For Modified 355 with 165 ECM ??
Going to tackle burn and tune on my 355. What would be the best bin to start with ?? Here is some info from my build.
TIA
Block
bored .030 decked .020
crank turned 10/10
Clevite 77 bearings
Speed pro hyper flat tops, -6cc valve reliefs, polished tops
polished stock rods with ARP bolts
cloyes true roller timing set
Comp cam CS XE262H-14 Lift In .464 Ex .470 Duration @.050 In .218 Ex .224
Comp cams lifters
balanced on a Hines
felpro 1010 .039 head gaskets
10.5 static 8.5 dynamic compression
Heads #128
Port matched,valve pockets,ports and chambers ported and/or polished
Crane 1.6 roller rockers
ARP rocker studs
Crane stepped guide plates
Crane push rods
LT4 springs
Guides machined and bronze liners installed
Deck resurfaced
Stainless undercut valves
3 angle valve job
Felpro viton seals on all valves
Intake
Super ram, port matched top to bottom, no cold start valve
52mm TB with air foil
Bosch 22lb injectors
Holley AFPR
No EGR
No AIR pump
Exhaust
Headman Elite long tubes with heated O2 in one and wideband in other
NO cats
Magnaflow catback

With an 86 4+3 car, I'd say your choices are limited.
An 87-88 4+3 bin would be preffered for the 160/8192 baud diagnostics, but your 86 4+3 lacks the first gear switch.
The 87-88 bins don't have first gear detection logic like the 86 bins do.
The 87-88 bins also have some improvements in the timing tables, things like an additional WOT spark advance table which can be handy, and elimination of the cold spark subtraction, and coolant temp compensation.
This leads to a couple of possiblities.
I would probably start with an 87-88 4+3 bin like ABTR, ABTP, ABTZ, ABTU, etc. and live with or tune around the 1st gear od behavior. I don't think I'd go through the trouble of adding the 1st gear switch.
Which od do you have MK2 (0.68) or MH5 (0.62)? This changes a couple of parameters for 4th gear detection and 1st gear look ahead ok tps setting. I use ABTR which is for an 88 4+3 MH5 bin.
No CSV is not a problem since the crank fueling can be compensated.

This leads to a couple of possiblities.
- Stick with an 86 aluminum head 4+3 bin.
- Upgrade to an 87-88 4+3 bin, and add the 1st gear switch or live with od available in 1st gear, or patch the 1st gear detection logic from an 86 bin into an 87-88 bin.
- Upgrade to an 89 bin and patch in the 4+3 logic, this is probably the most difficult choice to implement.

MH5 OD. I'm not worried about the 1st gear OD thing. I only use OD on the highway and want to eliminate the auto OD that the factory prom has.
I need to do some more reading

Dan,
Shoot me an e-mail address via PM and I can send you some bins and definition files that will permit 4+3 editing.
I'll also work up a bin based on what I'm currently running with o/d off be default, but with changes for your gears (3.07 I presume), stock injectors and MAF, which differ from my car. I'll back off on the spark a bit also since you have increased compression. 200 on/180 off ok for fans? 850 idle rpm?
