I loaded the tune with FC-Pro but previously have done the data init and used the HC to just change the injector and AFM settings to go for a drive and see if it made a difference but it still had the problem then The logs I have from FC-Pro show everything normal except for the timing, where it appears pretty much the same as the chart from FC edit above. FC-Pro is good for logging as it logs everything and you can select any point along the log and it tells you all values at that point But it just isnt helping me at the moment Logged a run with the old power FC and the only difference is there are voltages at the AN1 and AN3 points, but these have nothing to do with the Power FC when the FC-Hako is disconnected so I think thats a dead end I pulled my TPS off and checked to make sure everything was working. And it looks like its 100% O.K emailed APEXi Pacific before so hopefully get a response from them. At this point I just want to send it back for repairs/replacement

Yesterday yes lol. And the only thing I found out was that my car wouldnt explode at 27psi This problem with the new Power FC is really confusing. I have exhausted pretty much all the things I can do to try and fix it so might just be in APEXi's hands now. Have emailed them about it

O.K i have made some sort of progress on this. It's not giving me the answer but I have found some proof that of where the problem lies, here is the explaination I've just been writing: So when lifting off the ECU should realise TPS is back to idle and initiate fuel cut to the determined point (As tuned, the F/C AC on and off) right. So I have a permanent wideband setup and driving around now I’m just noticing that its taking a little longer for it to realise the throttle is closed, it drops down in the 10’s:1 AFR momentarily before going right to max lean. Now on the old Power FC when lifting off it went quickly to full rich then quickly to full lean, which is to be expected. So the new Power FC isn’t making this transition as quickly for some reason. I think this is the root cause of the problem. Also if I stay off the throttle (In this case lets assume im in second) until the F/C window is reached and it goes back to having a readable AFR (Not just off the scale lean) and I then put my foot down, no such problems, it takes off fine. I'm wondering if its just the TPS or is it something in the ECU. It just seems strange that it works faultlessly on the old Power FC BTW, since the last post I have: Used FC Pro to pull the tune from my old Power FC, done a data init on the new one and put the new tune on it. Have completed the self learn idle again. No results Pulled the bridged neutral switch in case it thought the car was always in neutral, no results Awaiting a reply from Apexi america, hopefully they reply soon

Where these all complete new tunes from scratch or was data bought across from older Power FC's? I think they will have been complete new tunes but just something else for me to think about. Might try and bring the old tune over to the new power FC with FC Pro. Don't expect to see any change but The logging I did with FC Pro shows both RPM and Speed about where they should be. Revs slowly rising and speed rising very slowly till the Timing returns to normal at which point it increases faster

Yeah I find it weird that if its a dud its only this one thing but looking a bit that way I have some log files from FC-Pro if anyone wants a look

So apparently 27psi is all my cooler pipes would handle today. Consequences of not turning the boost controller back on Whoops

I've started another thread in Forced Induction, have put a chart of what the IGN timing is doing and listed all I've tried and worked out. Can save a log tomorrow and send it to both you guys, its weird what the timing is doing but.... (See other thread)

Nothing at all really, its just (Im told) a really old version and is slow to write and read data, which I have noticed compared to the new one. The new one for whatever reason shows the car having less knock, I always knew I was getting false readings on the old one so thats a really good thing for me. It was basically just available at a good price and I thought I would update before mine decided to die. But in saying that its never showed signs of dying before. I was trying to sell it but I may hang onto it for the moment till i can work out whats wrong with the new one

No go on that, doesnt make a difference. It seems to work ok for the first minute or so, all gear changes seem ok, but then it starts after that. i've graphed it in FC Edit (chart) and the timing goes crazy when it does this. Have done some dodgy paint marking to show whats happening. Its got me a bit stuffed as to why the timing is jumping around like it is and then so smooth when the gear change is quick: I hope this is just an isolated incident and not affecting all of the new Power FC's. Its bad news for me if so but good news for everyone else. Don't suppose anyone has a new one that can tell me if theirs does anything like this. Frustrating that everything is so good, and the car is running better then ever apart from this issue. It might not seem to bad, but you imagine making a snap decision at a roundabout to go through and then the car just goes nowhere for a moment, its not good EDIT: A thought has occured to me, am I running to much timing in the top row(s) (More then 40 degrees) and its cutting it back as a precautionary measure? I didn't think it did this but just a thought: UPDATE - No improvements as expected

The Wtr Temp (Cool) settings are the same as the old unit. Set at 0 retard at 60+ degrees I suppose I could try putting 1 degree retard in there to see if it just always runs 1 degree less then normal, and I can just bump all the cells up 1 degree. Its worth a try I guess Comparing the two (old vs new) Power FC settings in FC-Edit there is no difference at all in the Air flow curves for the VG30 AFM. The only difference is the IGN vs TPS settings which apparently arent used in the older versions of FC edit. Besides all this, as far as I know its the TPS that tells the ECU to return to the Idle map when at closed throttle (and perhaps this is compared with engine RPM also) Might try the Wtr temp cool vs IGN, retard it 1 degree at +60 and see what happens, but don't think its going to be the answer Thanks for the idea though, I'm open to any suggestions at this point. Its a bit frustrating, Thinking I might have to send it to Apexi

Have now tried unplugging VCT and going for a drive with no change (VCT plug is leaking oil, but its still clicking so sounds like its working) unplugged the wtr temp sensors, gauge one made no difference (didnt expect it to) and ECU one just made it stick in Cold start Does anyone know how to extract the information from the Power FC so you can view the coding, I've seen lines of code from power fc data before, but cant work out how to extract it at the moment, going to compare old with new to see if theres any answers in there.

while I'm at it:

There we go

I thought I'd start a new thread for this seen as I was stealing the other one a bit. And I think this might be an issue if it turns out to be a problem with the new gen Power FC's If you havent read the other thread I'll do a summary here. Basically the Power FC is retarding around 10 Degrees when going from closed throttle to any throttle input. It will stay at 10 degrees retarded for about 1-2 seconds then go back to normal map at which point the car surges forward with a power boost. It appears like its going to the idle map then taking a second to realise its off closed throttle before reacting This is a graph on the HC of timing, showing what is happening: White and Red are gear changes where it is retarding the timing Blue is a normal gear change with normal timing So far I have tried: Adjust TPS - No change, except when adjusting it to far so it didn't go into the idle map at all Data Init - Changed injector and AFM settings only and went for a light drive, no change Changed TPS vs IGN - In FC Edit, every value to 0, no results Played with the IGN map - no results Disconnected and turned off the boost control Kit - no result Below 60 Degrees, everything works fine, so it must be fine in the cold start map, but as soon as it goes to std map, something goes wrong I'm hoping its not faulty Power FC but I guess if thats the case I can get a replacement. Have emailed Apexi USA about it so hopefully they have answers Any help is much appreciated, its frustrating me quite alot at the moment, considering my ancient Power FC (V2.20E) doesnt have this problem and then new one does.

Thats the one I dont know whats going on, It seems whenever I go off throttle completely for about 1 second or so it goes to the idle map and then takes 1-2 seconds to relise its at WOT again and go to the normal IGN map. If I back off in any gear and watch the timing as it decelerates it sits on the normal map (about 35 degrees I was watching it at for a while) and then as soon as I put my foot down, any gear, any revs it goes to idle map for a second then back to normal map. Does not happen when below 60 degrees So in cold start map it works fine, couldnt fault it once, but as soon as it hit 60 it started doing it. Have tried setting all the TPS vs IGN to 0 (inc TPS voltage values) with no result, tried data init with no results, tried adjusting TPS with no results except when you go so far that it doesnt go to the idle map anyway. Old Power FC works faultlessly when I plugged it back in. I might stop cluttering up this thread now, If someone wants to PM me with anything that might help then feel free to, it will be more then appreciated, Im getting quite frustrated with this. But at the moment I'm nearly thinking it might be a defective Power FC perhaps the TPS but I dont see how

Most of the settings that you need FC edit etc for don't really get touched usually so you should be fine to do it all with the hand controller (I don't envy that job but) just make sure you have your injector data as well as checking everything for settings they have adjusted (eg pressing next when at the air flow meter selection screen to make sure they havent changed the air flow settings) On my situation, Have had no luck, but it appears as though the TPS vs IGN wasnt a feature on older versions of FC Edit as the saved data I have doesnt have data for this section but I can read it off the old Power FC. Not sure what the go is there. Getting a bit frustrated with it, might send an email to datalogit and see if they have any answers. I've exhausted pretty much all the settings that I can play with so think I will just have to live with it for now till I get an answer from someone

Have had a play this morning and data init does nothing, driving on the base tune with only the injectors and AFM settings changed weilded the same results. Plug the old Power FC in with the new HC to eliminate that and it works perfect However I have just noticed that when I load an old tune into FC edit now it is missing TPS vs IGN data. This data is non existant in the old power FC's it seems so I think I will try setting everything to zero in here At the moment the values are all set to do nothing to the timing at any voltage of the TPS but this might be where the problem lies. If anyone has an older version of FC edit (pre 2.130k) and can confirm that this TPS vs IGN section is missing then please let me know as this might be what the problem is

Didn't Mclaren say they matched the offer but Hamilton wanted a new challange?

It appears to happen at all RPM, Its just not as noticeable when your pushing it harder becasue I'm already in an RPM range where the timing is around 20 degrees anyway, so its not as noticeable. I think I'm just going to do a data init and go for a drive under low load and see what it does. I think it might have inhereited something it doesn't like from the old Power FC. I've emailed Apexi about it anyway. Hopefully someone on here has an Idea but Closest thing I can see is IGN Dwell vs RPM, but its no different to the settings I had on the old one

Its noticeable. Feels doughy until it goes back to normal timing and you feel it pull harder. Its got me I've looked at everything I can in monitor and sensor check and everything looks normal bar the timing. Have tried playing with the idle settings, disconnected the boost control kit and adjusting the tps. The only way I can get it to work is to hold a slight amount of throttle on between gear changes

The calm before the storm..........

should say "Shutup, I know what I am doing"

Can't Leon do it? There used to be all this rage about Boost Motorsport, but I never actually heard anything good or bad, or now that I think about it anything about any work they did. I didn't think they were in existance anymore

lol yeah it should make it a bit more equal, But I still see Red Bull and Mclaren at the front It will be interesting thats for sure

I somehow don't see the Mercedes being a front running car even with the new engines not straight away anyway, they may get there eventually. Honestly I don't know why anyone would want to leave Mclaren at the moment. Sure they have had a few failures, but my god that car is quick at the moment. Red bull maybe still has the edge in the corners but it can keep up and then on the straights it just motors past
