ho did u know it was pinging?? was the knock reading over 60% on the h/c ?

this powerfc sounds interesting....

i have not owned or study it at all....although i did test drive an r33 which had one installed... it went nice and hard....

can you tell me how much they cost and where i can find technical info on them?

after using LINK, Wolf 3d, Haltech, seeing what motec can do and studying autronic, i would love to compare.

what are big power mods Al? Is big power mods defined as

- Larger Injectors?

- Aftermarket Cam Shafts?

- Aftermarket Turbo?

- FMIC?

- Big NISMO Sticker?

First three. Forth can be delt with by the apexi, and the fifth by the wanky ricers :P.

The best programmable ecu, is the one your trusted mechanic can tune. No use having a Wolf if he has only delt with a Pfc and isn't able to extract and use all features :uh-huh:.

But if you plan to change the first three items listed above, do the ecu first, as this alone will give you a noticable differance.

Good luck with your decision

rs73 - yepp, that's my understanding.

I've heard 'stories' of people pluging in a new PFC and gaining 15rwkw just from the base map it comes with..

Not sure how true this is, but sounds tempting.

u may get a slight power increase but the car will be pining off it tits as the fuel maps r based on jap 104 RON fuel

i wish it was that simple that the best ecu is the one your mechanic can tune the best.

Personally i would, and have always had my cars tuned by the workshop the particular ECU company recommended to tune, supply and fit.

Al,  

why you wouldn't wanna change factory IC with FMIC, considering with afm injectors, cam, & turbo?

what would be the factory IC efficiency is, don't think it will be effective for boost above 12 psi.

The original question was: what do i consider big mods to justify a ecu replacement. If you only plan to go as far as a fmic i am suggesting to use a apexi safc to trim the fuel curve. Of course you need to replace that shitty factory ic. If you are planning a turbo upgrade, etc. than a replacement ecu is a priority.

    • Good to know, I feel like I am in for a rollercoaster ride that looks like a sine wave. 
    • You'll fit right in. Acceptance is the first step.
    • Hey folks. I've been lurking and browsing the forum for a while, since I got into my head that I wanted a skyline. Having purchased an overpriced completely stock GTT, (only "mods" it has is HKS pod filter and catback) now that it became legal in the US, it was all glorious and sututu noises here and there. But then I wanted to do things right and went to do basic maintenance. After all the fluids, filters done, I did the spark plugs, that's when the problems started.. First the car started spluttering at around 4.5k RPM. Which I gapped down the new plugs and that solved the sputter there, but the car now always misfires at idle with pops when lifting off and shifting 2nd to 3rd. Similar to the issues in this recent thread. I've been banging my head against the wall, reading the threads here and trying suggestions for a couple months now, so decided to start this one to explain exactly what I tried and what is going on. The symptoms of the issue: Idle and low revs misfiring intermittently. You can hear the exhaust tone change and the shakes on the shifter knob. It happens frequently, but doesn't seem to have a rhythm to it. Pops when backing off throttle. It pops and or burbles almost feels like it spits fire when it pops. (Happens mostly in 3rd gear at around 2k RPM). When under load and after 6k RPM, it also pops when shifting from 2nd to 3rd. There's a ticking noise at around 2k RPM in 2nd gear going downhill, seems unrelated though but I am out of educated and downright dumb guesses. Not noticeable lack of power when putting the car into load. The attempted diagnosis and solutions: Unplugging coils when the car is running This did nothing to change the idling and tone shift for every cylinder. Checking the exhaust headers with thermometer They all are within what I'd say it is margin of error of the laser thermometer New spark plugs Tossed two new sets, copper, iridium and using the old ones, still misfiring, even re gapped to 0.8mm, still same thing. MAF cleaned with the "specific" spray cleaner No changes in the issues what so ever. Brand new loom and r35 coil conversion (was going to add the r35 coils anyway) car runs arguably better, still misfires, but seems like does less frequently. Placebo? Code 21 now being thrown, thanks nissan gods. Removed the CAS to check the shaft for play or anything. CAS seems all fine, nothing that indicates any issue, visually speaking. Things to attempted next: Ordered a new MAF (chinesium from Amazon, to be able to return regardless of result). Fuel with proper gas, maybe it is this California water that they sell as gas that is to blame? Plugin the link ECU and check the info using the built in base map. Go back to BMW and eat my rob bearing breakfast without milky oil mixture.   Do any of you have experienced anything like this or have any suggestion?
    • Yeah, all good ...got your postal addy as well ; I'll box the stuff in the next couple of weeks, you can paypal me later..
    • Hello! I had a mid life crisis on a budget and coincided with the R34s being legal in the USA. And now I am here, with it having old car problems and me slowly hoarding parts to start building it to what I envision. Essentially I made a mistake, that lead me to join this forum filled with legends.
