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.

    • Yeah pretty impressive hey, good to see quality products not over-shooting their prices. That's what drew me to buy the hypergear turbo, just a shame I've never got the chance to see it in action
    • Thank you GTSBoy and MBS206 I have done the compression test with the motor out of the vehicle, reason for the test was to see if I needed to remove the head and do rings etc while its out. I'm in the process of respraying the vehicle and tidying up a few things. Story behind it all is I've just purchased the skyline and it was running when I got it, never drove it on the street though as I wanted to pull it down and do it all up again before registering it. the gentleman I purchased it from told me the motor has a forged bottom end and has a decent tune through it but I was going to pull the sump off anyway to see if it is a forged bottom end. that's why I thought id do a compression test beforehand. 
    • Man, I'm kind of amazed that the price of the turbo has not changed in 7 years. Everything else is inflating beyond reason, but not this? Good on Tao / hypergear I guess? Anyways, good luck with the sale!
    • I'm selling my brand new, in the box, never used Hypergear ATR45 - and I had some additions I paid for a few yrs back when I purchased it. Never ended up having the rest of the money to add all the mods at once, so I just ended up slowly selling each part. I originally had it internally gated, with the dump pipe, however I found it was incompatible with what I was going to use it for, so I contacted (I think Ken) from Hypergear, and he and I messaged back and forth & he got me to ship the turbo back, where they modified it & made it externally gated, and gave me the 5 bolt dump pipe attachment for custom welding. (Photos below) This turbo like I said has never touched the inside of an engine bay, it's completely brand new, never used, been sitting in the same box it arrived in, covered in plastic & all. Below are the photos of it: And while the guys at Hypergear were making it in-shop, they sent me some photos of the process: I'm looking at selling this just because I'm in need of the money right now, and don't have plans on modifying the 34 anytime soon - and from reviews & peformance sheets, this turbo had amazing results back when I was researching. The turbo was purchased in 2018 for $1.9k, with the mods I got added on. Looking at the website now, for the same turbo they sell (ATR45SAT), with the current addons it adds up to $1830 for the turbo Current addons included: - Bolted dump adaptor - Ball bearing CHRA - Braided oil feeding line So I'm looking to possibly sell it for around $1800, with shipping included in that 1.8k, It cost me around $120 to ship - so yeah thought I'd throw it out there and see if anyone was interested in purchasing. Cheers!
