KKtrips Posted October 25, 2023 Share Posted October 25, 2023 @Vk304, I did not know Mace made a roller cam for the Iron Lion? When I was researching for mine, all of their 304 stuff was for flat tappet cams. Quote Link to comment Share on other sites More sharing options...
Vk304 Posted October 25, 2023 Author Share Posted October 25, 2023 Yea its their next generation products i guess, i believe its a crow cam just rebranded? I brought it as it was cheapish and had all the parts, they sent me the wrong memcal tho so gotta wait for that now haha. Probably not a massive power increase but should sound mint ay Quote Link to comment Share on other sites More sharing options...

Crane did them but they were well over a thousand bucks just for the cam. I wrote this response before you posted above but it might be worth saying for others knowledge, if its a cam designed for a flat tappet and you use it with roller lifters, it will fuck the roller wheel, a flat tappet cam has a very slight side to side slope on the lobe to rotate a flat tappet lifter and a roller lifter on a flat tappet profile will mean all of the valve spring pressure will be concentrated on one side of the roller wheel. It might be OK, but I would be not wanting to risk it. 1 1 Quote Link to comment Share on other sites More sharing options...
vk327 Posted October 26, 2023 Share Posted October 26, 2023 beware of the mace memcal they are spotty at best for actually being tuned, definitely throw a wideband o2 at it and check fueling is safe, going off prior experience will have bugger all timing in it as well 1 Quote Link to comment Share on other sites More sharing options...
Vk304 Posted October 26, 2023 Author Share Posted October 26, 2023 Good to know, itll get it driving at least, tuning and electronics is not my strong point so yea definitely will have to look at a wideband to monitor it, when funds allow. .

Muncie Posted November 7, 2023 Share Posted November 7, 2023 Your "big chip" might be an NVRAM to allow live tuning over OBD not something I've used but if you swap out for a stock ecu your mace chip will drop in. Or get someone on pcmhacking.net to send you the .BIN file and flash it onto the existing ecu yourself. 1 Quote Link to comment Share on other sites More sharing options...

Id need to find someone to help load it, ive been on pcm hacking and all the lingo and ecu programming just confuse me lol, This chip is on a vs long type holder as opposed to a vt short type (as used in roller cams), i had the original chip made to delete factory security and run my vk setup, but now have a cam so need to find one to suit. I cannot swap it out for a stock vt ecu as its a vt roller block with a vs ute ecu that runs on MAP/multi point injection as opposed to vt MAF/AFM/seq injection/knock sensed/different wiring. Ultimately the solution would be to run a roller cam tune in vs memcal like the one ive got.. but mace is a bit slow in replying if thats possible.

vk327 Posted November 9, 2023 Share Posted November 9, 2023 have a chat to trevor at holden diagnostics, you might be able to talk him into setting up the memcal you have in your current ecu, hes still does all my v6 and v8 memcal stuff 1 Quote Link to comment Share on other sites More sharing options...
