Possible to read tuned memcal with comms?

[john59903]

Cam is
212@.050
113 LC
And .470 valve lift
If that helps

Thinking I might make two tunes identical with one that drops timing to 30 degrees at 95-100% TPS

That is a lot of comp for a cam like that (is that a crow cam for high ratio rockers?). Certainly explains the very high compression readings.

I'd be taking a couple of degrees of timing out right through the map to start with.

Idle will be rich but it will start to lean out as the rpm gets up and the cam comes on.

It's a Clive 48a cam I'll take your advice

[john59903]

And I would like to go a little bigger with the cam but the one I have is fairly street friendly and still allows me to get 1.8 rockers if I choose to it makes fairly good power as is and has run a best of 13.8 @99mph

What engine is this in?

Buick/ecotec V6 can handle about .515" total valve lift with standard springs/retainers although I would imagine you have upgraded the springs to suit the cam. .470" lift is fairy conservative.

Buick will only go 0.495 lift before seal to retainer contact

Hey guys another quick question, were would I get instructions for soldering the comms to the ECU? Mine arrived without any yes it's a genuine PCMhacking.net comms and NVRAM but I bought it from a guy who bought it to tune his car and then lost interest

I'll send em via PM.
