Re: Turbo Boost Reference Chart

Vince,

The  89-90 200TQ and the 89-91 200T with the dual knock
sensor MC engines with higher compression (8:4 to 1) that
use the MAC14 ECU do have a boost control map with slightly
lower boost settings when compared to earlier MC single
knock sensor engine (7:8 to 1) with the MAC11 ECU.

Here are the following values used in the MAC14:
RPM 			2000 	2975 	4000	5000	5325	5575	6000	6375>
Boost map value	1.36 	1.38	1.37	1.375	1.39	1.39	1.38	1.37

The MAC11 uses these values:
RPM			1000	2000	3000	4000	5000	5500	6000	6375>
Boost map value	1.04	1.35	1.4	1.4	1.4	1.42	1.4	1.4

Send me a private email if you want more details on ECU
mods for
the MAC11 and MAC14 ECU's.

Cheers
Scott M.
