Break points air-density injection	3620-363f	air dens (mV).:0.5 0.701 0.799 0.901 1 1.201 1.5 1.7 2 2.3 2.65 3 3.5 4 4.5 5(full throttle)			Idem
Injection mapping	3640-373f - 16curves of 16 bits	Every curve is a particular air ensity, every bit is a particular rpm.
Injection enrichment (kick down situation)	37d0	1 1 1 1 1 1 1 1.04 1.06 1.09 1.11 1.16 1.19 1.22 1.19 1.06		rpm setup by "rpm breakpoints"
Injection distribution	37fo-37ff (when injectors open, degrees on crankshaft)	450 450 450 450 495 495 495 540 585 585 630 675 675 720 720 720		idem
Air temp sensor 3800-380f Water temp sensor 3810/381f	3800/380f Bit > Air Temperature correspondance table (mappa 2d): corrispondenza tra valori binari e la temperatura dell’aria (da -30°C a +130°C). I valori variano tra 0 e 255. Permette di impostare la definizione della conversione in binario delle zone di temperatura rilevate dal sensore. x il calcolo usare la formula: val= 0,625(T+48) T=0,625(val-48) T= temperatura in gradi celsius
Ignition during start 3900/390f	3900/390f Mappa accensione in trascinamento (mappa 2d): tabella che stabilisce l'anticipo durante la fase di avviamento. Coordinata X giri motore, coordinata Y angolo anticipo accensione (definizione 0.25 gradi) nb: il regime motore è calcolato con il breakpoint all'indirizzo 3940/395f x il calcolo usare la formula: (val/4)
Breakpoints rpm ignition	3820-383f	600 699 900 1000 1199 1400 1599 1799 2099 2600 2898 3199 3803 4401 5193 5990			A competition engines usually runs in hugher rpm conditions than a street engine, so ECU muast have more attention set to higher revs situation (but don't forget knocking problems!!!).
Breakpoints airdensity ignition	3840-385f	0.5 0.7 0.98 1.2 1.7 2.3 3.0 4.1 4.7 5.3 5.3 5.3 5.3 5.3 5.3 5.3
Ignition mapping	3860-38ff - 10 curves with 16bit
max turbo pressure	3b95-3ba0
max constant turbopressure	3ba6-3baf
turbo pressure limiter	3bb7-3bbc
turbo pressure cut	3c10-3c1f	c9	ff
turbo pressure distribution	3c20
rpm limit1	3a60-3a6b (0101)	7295 rpm		1875000/257=7295	0101 means 257
rpm limit2	3a6c-3a6d (010c)	6996 rpm		idem
Misc notes: 39ef a 3a7f c'è la possibilità di scegliere il tipo di piano quotato da attribuire alla mappa base ini e acc: farfalla o pressione e così è anke x il battito in testa..es: 0=abilita pin6 1=disabilita pin6; adress 3910: correct inj e ign depending on temperatures; 3770/378f breakpoints temp h2o and rpm 3790/37cf cold start enrichment 3740/374f correct inj depending on battery voltage, from 6 to 16volt, with steps of 0.667V... breakpionts rpm = 1875000/dec.value (16bit) breakpoints densità aria: value/575 OR (value/895)-0.8 =press (bar) Inj time (0,064xVAL)+1 Ign phase (VAL x -2,81)+810 enrichment kick down val/128 Ignition time val/4 calculus for injection phase, the true one: =450+90*(128-VALUE)/32 dall'indirizzo 3910 si trovano le correzioni della mappa ini e acc in base alle temp
Modify at your own risk. I'm not responsable for any damage may occur to your engine!! BEFORE TESTING?? DON'T TEST THIS!!!!!!!!!!!!! In order to get best performance from this file you need: 98ROM min. fuel, uprated exhaust system, new sparks and air filter, engine and turbo in best conditions. Try also them with a Vmeter connected to your Lambda sond (or install it if you haven't ) and with a exh. temperature sond. Temperature MUST be less than 830 C° and Lambda signal not less than 0.8V. Try in full charge situation (left feet pushes on the brake pedal and right feet kick down on the accellerator) in 4th gear for noit less than 20 seconds
