I already know that the software that came with the hahn portfueler is very lacking in its datalogging capabilities as well as under-programmed for features, but the same company that makes hahn's portfueler controler also makes a few controlers that may satisfy the needs of high boost peeps.

I am not comparing the products to megasquirt, because I am very confident that megasquirt is already a better solution. It should be said that there are other ways to control timing for high boost applications. www.splitsec.com has said that these controlers have map sensors that will accomadate to 26psi.

for the people kicking themselves for buying the portfueler instead of megasquirt can go with this option to adjust spark timing:

price = ~$380

They also make a programmable fuel and spark controler in one:

under the FTC1

price ~$550 (if i remember correctly)

cheers.
