1990 Lancia Delta
Integrale 16V
16VT’s involvement: Re-calibrated stock ECU in
real-time using wideband
to suit turbo setup.
Chassis: stock;
Forced induction: Garrett turbo with T4 N-trim turbine
wheel (52/74mm) in stock 0.48 AR housing, T04B V-trim compressor wheel
and
housing.
Engine: 2000cc, 16 valve, free-flow
filter & exhaust, stock compression.
Injection: Port
injection, stock 058 384cc/min injectors at 3.6 bar FP
Description: Change of turbo mandated recalibration of fuel and ignition tables. Emulator was used to map the vehicle on the road. AFR of 11-11.5 was used at boost and 15 everywhere else. 5000rpm lanuch control added via secondary EPROM map.
Burning two 256k maps onto a 512k EPROM:
MAP
1 is located from 0000 to 7FFF, obtained when A15=0 (launch control)
MAP 2 is located
from 8000 to FFFF, obtained when A15=1
A15
is pulled up to 5V through a 10k resistor from pin 28 (VDD) to obtain
A15=1
