adi2009 Posted November 14, 2008 Share Posted November 14, 2008 I m pretty much going in for a brand new engine into my TT with a T61 single setup. I m going the standalone route with an Autronic SM4 ECU and CDI unit. My question is, do I get the tuner to initiate the tuning process right from the breakin stage or should I put the stock ECU in for a break in and run off boost for a couple of hundred mile first??? My setup would be: Brand new blueprinted OEM shortblock, new stock head with entire new OEM valvetrain, HKS 264 In/Ex cams, PHR single valve springs and retainers Also, is there anywhere I can get proper engine breakin instructions?

tooquicktostop Posted November 14, 2008 Share Posted November 14, 2008 I would have the mapper there on start up and run the stand alone, the stock ECU will not work well with a single, it is very important to get the base map right before you use the car Quote Link to comment Share on other sites More sharing options...

foodfreak Posted November 14, 2008 Share Posted November 14, 2008 Change the rod & main bolts for arp's for a start. Proper ecu / map from initial start up. Run in on mineral based oil for the 1st 750-1000 miles. don't 'rag it' or place heay 'load' ( low rpms/ high gear) on engine Quote Link to comment Share on other sites More sharing options...
Guest murarie Posted November 14, 2008 Share Posted November 14, 2008 +1 on above Posts. OT - Any reason you decided on the Autronic SM4? , AEM has a Plug and Play ECU with custom base maps you can buy online so you can be up and running and then tune with a wideband. Makes it a lot easier if you don't have access to a dyno. Quote Link to comment Share on other sites More sharing options...
johnd-mkiv Posted November 14, 2008 Share Posted November 14, 2008 Mine was run using the oem fuel setup and ecu with no boost for 1000 miles then the fuel system & ecu upgraded and full mapping carried out Quote Link to comment Share on other sites More sharing options...

I got the Autronic because I didnt specifically intend to use it for the Supra, was going to be a project on another engine but canned that plan so I m now planning on using it on the 2JZGTE. The Autronic SM4 coupled with the 500R CDI unit is supposed to be one of the most reliable and on par with Motec's. Quote Link to comment Share on other sites More sharing options...
