Did you put a nite in your PayPal payment as to what it was for? Have you tried contacting him?

I have some questions about TephraMod V7:
1. Can I use MAP sensor on anything Evo VIII ECU or I need specific ECU? MAP from Evo X. By default TephraMod is have Evo X MAP scale?
Yes you can use the map sensor such as omni 3bar, omni4bar, aem5bar, jdm3bar but you will need the correct scalings for that map sensor.
2. I will use firmware on Evo VIII. Can I disable some OBDII errors? Because it's rally car and many arrangements and sensors had been removed.

yeah finally

First of all I would like to thank everyone who has contributed to the development of this, I reckon some of the new features are awesome

Secondly if you would like to donate just PAYPAL whatever you can/want to donations@globalshare.net

FEATURES

Flashing CEL on Knock
- slow flash for low knock
- fast flash for high knock
- low and high knock thresholds customisable
- minimum load threshold customisable
- can get it to drop boost if above the High knock threshold

Valet Mode
- customisable RPM limit
- autovalet on fresh ignition (ie if you leave the car and come back it will auto valet, as opposed to returning to the previous state you left the car in)
- NOT able to co-exist with TPS based map switching
- CEL will fast flash on ignition if valet is enabled

Alternate Maps
- 3 methods of switching maps - ADC0F (ie Jack_of_Trades harness OR meth failsafe), Intercooler Auto Switch (ie hold down for prescribed time), TPS switching (ie hold TPS like Valet mode)
- all 3 methods WONT switch TO AltMap when car is above load threshold
- ADC0F switching WILL switch BACK to Normal Maps if voltage drops below threshold - hence meth failsafe

BIG MAP
- changed ECU to use new BIGGER MAPS for both Fuel and Timing
- same axis's for both sets of maps
- altmaps and launch maps included
- LOW OCTANGE FUEL AND TIMING INCLUDED as well
- does NOT affect other timing maps, ie EGR or ColdStart
- both Fuel AND Timing use the same Load that the Fuel maps would normal use (ie Load_Baro_n_Temp_Compensated), please keep this in mind for high-altitude tuners

2byte to 1byte load factor
- simple divide routine to convert 2byte load into a 1byte field and then Evoscan will convert back to 2byte.
- MATCH you LoadFactor in ECUFLASH to the SAME as your Eval in evoscan
- MaxLoad is loadfactor * 255, ie a loadfactor of 1.2 will allow a Max Loggable Load of 306, 1.3 = 331... etc (choose an appropriate loadfactor based on your existing max load)

No Lift to Shift (NLTS)
- basically set's a revlimit of whatever your CURRENT RPM is (ie when you shifted) MINUS the RPM Drop you specify in EcuFlash
- Various thresholds ie TPS/Speed/Load so it wont activate by accident
- If you do have problem's its probably your top clutch switch.
- Always do the garage test (ie set speed to 0, tps to 20, load to 0 and then practice the engangement point whilst idling)

AFR Safety
- REQUIRES WB02 wired upto the rear02
- various thresholds and timers
- will Flash CEL AND/OR Drop boost

Launch Maps
- Allows you to customise your "Launch" igition and fuel maps
- various thresholds so it only activates on Launch
- Should override altmap mode as well

FULL Gear based boost control
- removed existing BDEL and BWGDC tables
- added new 3d tables with gear on the X axis
- allows you to have different boost levels AND wastegate duty cycles for each gear

TPS compensation for WGDC
- Basic multiplication table for WGDC

MAF IAT compensation for WGDC
- Allows you to add or remove WGDC based on intake air temp

100% WGDEC under a certain load
- Keeps BCS from openning wastegate under a certain load (to aid in spool up)

Preconfigured MUT Requests
MUT00+MUT01 = 2byte airflow (ie MrFreds mod in g/s or lb/min)
MUT02+MUT03 = 2byte airflow (ie MAFHz)
MUT40 = 1byte gear
MUT41 = 1byte load
MUT42+MUT43 = 2byte SPEED/RPM ratio (to get your gear ratios correct - if you need to)

2byte load AND 2byte RPM are no longer included and IMHO not needed!

INSTALLATION

Wiki Page

This time all you have todo is make sure you have a recent copy of EcuFlash (1.41+ is good) and you just COPY the entire .xml file into your EcuFlash XML directory. No more patching xml files.

BIG WARNING
Whilst I have tried to test everything as much as possible it is up to YOU to test each feature before driving your car around! If you notice any WEIRDNESS (including EcuFlash showing funny values for things) please post up so we can help you! No warranty is provided, and any damage done cannot be held against me!
