Phil, what do you think the advantages are of a stand alone over the stock ECU? I will probably never get one, just wondering what advantage they have over piggy backs (aside from rev limiter ajustment). Seems as if the stock ECU does timing advance just fine, at least for those of us running pump gas boost.
Standalone's biggest benefits are:
1) You have much more control over every parameter in the computer. Cold temp fuel map adjustment, closed loop throttle percentage, etc. Even the standard fuel map and timing maps have many times the adjustability of an SFC/AFC/GCC and/or ITC.
2) Adjustments to the map in a standalone ecu are very stable. There's none of this "I'm resetting the ecu because I'm switching from pump gas to race gas". For example, the fuel map is set in milliseconds of pulsewidth on the injectors (not a "click" or a percentage point relative to the oem fuel map that is constantly changing due to closed-loop). This means that performance is very consistent and repeatable.
Well they're are so many to choose from how do we know which one fits are needs... I mean some people are sending in their ECUs to UPRD or GForce (maybe same thing just dif price) and call it a day. I believe the GForce only removes the need of the BCC/FCD but I haven't had it done I dunno it makes the map 10x better.
So if I get a GForce Upgrade what's the point of a standalone in my situation and which do I need or wold want..? if ne1 can even answer that question.
After I have installed all the new seals, BCsprings, retainers, locks and buckets,
with T-belt off, put crank at -10 btdc so all pistons are slightly down, install new BC 272 cams, install cam gears, torque cams as per manual. Then turn CAMS clockwise to tdc notches, and than turn CRANK to tdc...
Recently acquired a rhd supra and slowly starting the process of swapping things over. Got myself some glass headlights and wanted to swap bulbs while I’m at it. Been told jdm lights differ from usdm. Hard finding more info on this. Thoughts? Trying to find a quality hid system, seems LED isn’t...
Just installed a pair of S2 taillights on my 93 Supra RZ. I would like to convert to LED. I would like to purchase from here as the prices seem very good.
According to my search in the Forums, looks like I need 2 x 7440 and 2 x 7443 bulbs Just not...
I had a boost leak on my 94 BPU for years and didnt notice it because I still got good boost. So I finally fixed it but forgot to turn my boost controller down. I hit 25 psi 2 or 3 pulls without realizing it. Since then it wont go much over 14 psi anymore.
I did a boost leak test for...
