Good morning every one, could any one tel me if the Apexi Super AFC vould do any good to my 91ZX Manual non turbo, and if yes what vould I gain, thanks boys
Would these be of any great benefit on a TT if I was planning to get the car dyno tuned and 'chipped'?
A socket, ecu chip and dyno tune does everything that a SAFC can do + more. However, once chipped, if you want to make changes, you have to re-do the whole process again. With a SAFC, you can make changes to the A/F ratio anytime, anyware. But, like I said, it cant do all the things a chip can. Benefits of chip + dyno tune: increase rev limit, remove top speed limiter, tune fuel maps, timing maps, if boost controller is installed then add boost as well, to your cars specifics, all done under the supervision of a dyno, so with a sensible tuner, it should all be done safely, ie they can see when it pings, will back off the timing etc A SAFC only allows you to adjust the air/fuel ratio, and does this by fooling the ecu. The main benefit for a SAFC is, like ZDUCTIV has said many times, is that it will allow you to run dual MAF sensors. So if you have all your mods done, then save your $ and just get a dynotune.
I was also thinking, unless the ECU can run two maps (?) a SAFC can be set to run for good fuel economy normally and for high boost at other times.
The stock ecu can already do that. Different parts of the map for high load (high boost) and low load (cruising). As for the original question: SAFC for NA's. Rechip/Piggyback/Standalone for TT's mainly based on the need for expandability in the load that the stock ECU can handle (around 13psi), as well as ability to adjust timing, and alter fuel maps three dimensionally.
