Best SD rom for USDM evo 9
Hi guys..
I want to know which is the best SD rom for USDM evo 9
with complete tables of ISCV disassembly and Idle tables.
- The rom available in SD 2.0 thread doesnt have different map sensor scalings as in other evo 8 roms.
- Target Idle tables
Any explanation for this ?

Yep 8859- so after alot of searching and help from a few friends I made the xml updated.
There were a few incorrect addresses and scalings.

I cant find the Post Cranking Enrichment tables and MAF compensation tables for this rom.
Interested to know how you adjusted the cold start ..

I've added a few things to my 8859.
- Fan control (its hot as hell during summer)
- startup fuel
- fuel pump control
- wideband o2 for CL instead of oem oxygen sensor (needs testing)

Damn --- I totally forgot -
Mfred just found some fuel tables for 8895-
Evo9_dubai : were talking about the same tables from Mfred's thread ?

i added the wideband closed loop tables from mrfred but i never ended up using that rom. i have had really good luck running full open loop.
my startup fuel took a long time and a broken starter to get right. i have lsx coils that are extremely hot so i had to reduce dwell and fuel to keep it from kicking back. its still a little finicky starting once in a while but its a race car, right?

ls truck coils (D585) are smart coils, you cant run cdi with them.
they are extremely hot coils, so much so that they erode the electrodes off iridium plugs and i have to periodically reset the gap.
the stock ecm can control them directly, if you make a harness to adapt to the stock wiring they work fine, you just need to lower your dwell tables appropriately.

On the LS1 coil there is around 40 milliamps of peak secondary current with 5 milliseconds of dwell time. On the LS2/truck coil (AC Delco D585), there is 120 milliamps!

How are your cold starts ?
