I've done many many many jump starts with my PowerFCs and had no problems.

This is how I jump start cars:

1. Back cars up together

2. Connect cables

3. Start the car with the good battery

4. Leave for 5-10 minutes to trickle charge the battery in the flat car.

5. Start up the flat car, and immediately disconnect the jumper leads

6. Switch off the good car.

7. Go drive the flat car.

No problems with frying my PowerFC.

Tony,

Don't forget that I am purely speculating about my problems - It might not have been the charging at all.

PH1 had seen simlar issues where the PFC lost it's AFM settings - (I have Q45 so maybe not many ppl have set this way)

If anyone wants to try my PFC in their car, gimme a hoy - I'd be interested to see if it does the same thing ( ie not start ).

Damn cars - such a waste of money....... :P

I have had to jump start my car with PFC installed a few times now and had no dramas.

I beleive the most potential damage is to the car doing the jump starting.

Either way I have used an earth on the chassis of my car for the 'ground' and simply clipped the positive clamp onto the + connector under that cover on the drivers side under the bonnet.

Clutch starting has gotta be much safer for the electrics doesnt it?

Hmmm interesting - I wonder if that is all that is wrong with mine.....

Damn sewid - that must suck , having to re-program every time you loose power - Especially if you hadn't taken a note of the old settings - then you would need a re-tune.

Yeah luckily it hasnt been an issue yet because everytime i pull the power all i lose is the "boost controller" setting since im using the base map.

For now im running the stock ECU though since on the base map the knock detection goes over 80 sometimes (only did it once but took it off after that).

Ill open it up to see if there is a replaceable power cell.

I've already done that on mine - there is no battery in there - settings must be stored on NVRAM.

So do all your settings revert back to base map ?? ie if you change any timing or fuel settings, they also get reset ????

I reckon we should be able to find an electronics guru who could fix these things.....

well i havent had my stock ecu fry so i dont think the power fc would be any different its still a ecu and but i just remembers more settings. Apexi would of mentioned it if they had a problem with it ;) read the manual of the power fc (english) and my mate read the jap version no mention of it. Havent heard of anyone with a problem like this. My 2 Cents :D

I don't think you can say that - the PFC might have different electronic components and different power supply components and different voltage protection, etc.

They are two completely different ECUs. Designed and built differently.

Either may or may not be suseptable to spikes or surges.

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
