Jon V,
 
You must have miscalculated somewhere = along the=20 line. A small engine will never pull those big CFM = numbers.
 
{Engine cu.in x rpm / 1728 (No. of cu. = ins in a=20 cubic foot)} x VE =3D CFM
 
Ugly engines, VE =3D 75%
 
Highly tuned racing engine (at point of = max.=20 torque) =3D 100+ % VE
 
Tuned runner street engine =3D who = knows, it=20 varies.
 
To convert cc to cubic inches = (according to=20 Commercial Hydraulics manual I just picked up) multiply by = 0.06102.
 
Much can be learned about engine = breathing from a=20 file that can be downloaded at the following ftp site:- ftp://ftp.superflow.com.au The = file is=20 called Dynomation Zip. From this file, you can print the manual (Doc). = The=20 wealth of knowledge about engine breathing contained in the manual = is=20 exceptional.
You can try coming from the www.superflow.com.au direction. = Stop off=20 and visit Holden Racing Team. These cars use MoTeC ECU's. = Another=20 Australian ECU is the Autronic, but I have noticed that you guys = call it=20 something else. I think the US dealer must re-badge this race ECU. = Haltech=20 is another Australian ECU, but these are a long way off the mark when = compared=20 to Motec's logic, hardware, power and interface software. This is = my own=20 opinion of course. 
 
Totally different subject =20
 
A while back Motorola were putting out = an eval.=20 board for one of their Coldfire processors. It came with Integrated = Systems=20 C/C++ compiler, a communication card for the PC, a serial cable. The = debug=20 firmware provided debug / disassembly and everything that opens and = shuts. It=20 just seemed that such a tool might be a handy little number for = what most=20 are doing.

Anyone = familiar with it?

I have tryed to get some software to do the same....no luck yet. Have been in contact with Delco and Mark Laubenstein who made the hardware and Ron Gaskins who made the software . They are wery helpful and I feel they dont like the secret filosofy . Delco has the software you need Its called PC-CAL/PC-HUD. All the marinizers has this program and about 4 persons in US including Arizona speed and marine.You need to have an agreement with GMPTG to get the software. The person to contact to get this is Rich Waggoner M/C 483 720 210 GM Powertrain 777 Joslyn Aveny Pontiac , MI 48340 They adviced to contact him on phone first : 248 857 2321. Please keep me posted if you have better luck or find an other software Espen Hilde ------------------------------ End of DIY_EFI Digest V4 #503 ***************************** To subscribe to DIY_EFI-Digest, send the command: subscribe diy_efi-digest in the body of a message to "Majordomo@xxx.
