Volvo S70R built '01 B5244T3 LPT engine with ported RN *head, Dual VVT, but my exhaust side is fixed.

*2435cc 9.0 compression

*TD05/06 HRC 20G turbo

*3" free flowing exhaust

*FMIC

*550 Bosch injectors/ 850cc Bosch EV14 for ethanol

*Walbro 255 pump

---------------------------------------------------------------

*Wideband (any LSU4 sensor works)

*EGT (after turbo, in dp…should be relocated into the collector)

*Volvo COPs..dwell: ~2.1ms@14V (not sure if it’s the right value *for Volvo coil)

*Trigger setup:

**h[0]=08 02 01 04 10 20 40 80 /injetor fire order

**h[1]=00 60 48 30 18 FF FF FF /Trigger tooth

**h[2]=00 70 60 30 10 10 60 60 /Ign fire order

*Boost control: done, works with stock TCV

*IDLE: stock, works

*Tachometer: Can be Motronic or a pulled 12V output from vems (divider 20)

*Coolant temp: ECC also requires it, so we have two options.

#*Hook up Motronic, give pos, negative wires and only the coolant signals, but in this case you need a separate sensor for Vems, I used a RN one.

#*Create a small 2$ circuit to generate frequency to instrument panel: 40Hz-21Hz (20°-100°)

*WheelSpeed/roadspeed: not ready (VEMS boards after 2010 can handle 0-12v signals!)

*Knock control: not ready yet (works at my buddy)

*Traction control could be set up, but not so important to me.

*Climate control: produce 5°C/ 41°K cold air, works with most of the (important) functions. I had to hook up Motronic to achieve this. IDLE still drops a bit, but I can install a little valve which separately allows more air into Intake when M4.4 activate the compressor.

(What missing is compressor disengage control when WOT or high LOAD. I can live without that.)

​ Full automatic, monitors high pressure side, which triggers the fan low/ high speed depending on the pressure. Shut down the compressor over 125°C or above 30bar on pressure side... So it unable to overload.

Requires the following signals:

Power and grounds, "High" Pressure sensor, stock coolant signal, Pressostat "low" press switch, RPM signal, Low and High speed of the Fan

Future plans:

Fine tune start up time, shorter cranking from 2-3 seconds)

VVT control setup

EVAP control

Trip Computer: could be handled in the future, but not important, because Vems can display consumption in main screen, present and average also.

Former car setup on vems in 2010: Volvo 740

1st setup was: B230FT, ported 19T, port&polish 531 w/ 38exht valves, running E85, MS2 V3 Extra management system was until one year... Then back to Fred chips :P. -->280HP

2nd: T5 Swap: S70 B5254T engine with TD04HL-19T turbo. Goal is above 300HP on E85 fuel
