ecu cant pull enough timing?

[r34 gtr]

ive got my car running very rich with my safcII (terrible device by the way, NOT worth the money unless you just want to use a z32 maf or something) and im still knocking like a mofo. zero correction with my 510cc injectors. today (it was 105 degrees, thanks south alabama) and my knock meter read 55. just for an idea it reads 0 when the air temperature is below 80. so i was wondering if anyone knew how much timing control the factory ecu has. it cant be much, otherwise i would think it could pull enough to keep the knock at least sort of low.

on another note, does the power fc do sequential injection? its probably not worth buying as my iacv thingy is dead and it would still run like crap unless i replaced it (freaking $100!! its robbery!), as it uses all the stock sensors and stuff. i was thinking of just blowing all my money on a motec m400 pro so i could use the launch and traction control functions. it would absolutely ruin me financially though. i was going to use the megasquirt, but i have been reluctant because it doesnt yet do full sequential ignition. anyway, ive had enough of my car being near undrivable all the time. ive got to do something. let me know your thoughts

Bring your car to me and I'll have you squared in a New York minute. Tim, you've been at this for a while and you're one of the members that's been around a long time that needs to progress. For all the headaches you've been through, you could've installed an SDS and be done with srewing with your car for a while. Sell the harness and adjourning electronics as well as the afc and use the money towards a down payment on a good standalone, doesn't have to be SDS, but one that's worth your money. Think about and get back with me...............

ive got $2k coming to me in a few weeks. if thats not enough to cover it i dont know what will. sds sounds pretty good to me but im still checking on a few others. my subaru buddy suggested a hydra, and i might give it a look. dont know of anyone running one on a nissan though. im not that far away, and ive got friends in sarasota that would put me up down there. ill be sure to give you a call first. ive got your number and everything. (scary, isnt it?)

Scary it is, but doable as well. Whatever you decide, it's time to toss the factory crapola and move-up in the ranks of performance and flexibility.

I've heard Microtech makes a nice system and its pretty affordable.

From what I've read, the hydra nemesis is actually a pretty good system. That seems to be the top choice with most of the mr2 guys. That and the autronic. But I didn't think the hydra came in a universal form? All I can find on their site is for specific applications.

I do agree with Boost Boy. I've been reading about all the problems you've been having in the past and you've had some terrible headaches and bad luck. It seems like a good idea to sell the harness, ecu, and whatever else and put that money towards a stand alone. Much more flexible.

I think this is all tied into the SAFC. Because it works by altering the MAFS signal, it's screwing with your timing. The ECU doesn't pull back timing in a linear fashion in respect to the knock sensor. It is more of an on/off thing. If the knock sensor signal exceeds a certain amount, then it pulls back a bunch of timing. Otherwise, it runs normally.

I'm very happy with my SDS and would reccomend it to anyone. But as was stated before, ANY standalone that will control fuel and spark is better than what you've got.

i know your pain.i have been in the same boat with you.i would love to go with a standalone but i dont know if i can intall it right.i like the sds and would go with that one if i got one.too bad dee you live to far away.ihave been wiothout mine for over a year and cant stand it anymore.

Dude, you don't stay that far away! As for installation, it really isn't that hard, but the brackets and magnet placement has to be correct or you will be spending more money. The brackets I have made are from a permanent jig that my aluminum guy has set up for me. I just call with my order and they get made. They aren't too cheap, but in the end, the performance is priceless. No more crank angle sensor, nissan coil packs, no more afm, no more idle control section, no more cold start solenoid, no more headaches. I've been where you guys have been and spent a lot of money along the way and I know when it comes to performance, I won't be using the stock nissan electronics again. Now on my DSM powered hyundai elantra, that's a different story seeing that I reconfigured the stock elantra's harness to accomodate the eclipse's ecu, afm, and I even wired-in the eclipse's injector resistor and it all works perfectly. But nissan, no more.

What just for s&g's, what does an SDS run, and what would it cost to get you to install and tune it? You can email me if youd like, but im genuinely interested.

You got mail, dog!

yeah, i probably need a good ballpark on what this will cost. there are some other things that will probably need fixing on my car too.... it uh, leaks plenty of oil (where from?!?!!!), needs a fpr, the downpipe is stock, as is the 240sx cat... anyway, im sure an sds would do the trick. email me at

thanks!

capwred, im not any closer to dee than you. you have zero excuse not to blow all your rent money on a stand alone.

SAFC is very effective in capable hands. Good enough to take heavy 2L DSMs deep into the 11s. DSM has the huge advantage of inexpensive datalogger to properly monitor knock and ecu timing tho. We don't.Really have to understand what you're doing with a safc. The less correction, the better, so I'd pair the 510cc with maxima or z32 maf.

Maybe a 'resident ca18 ecu tuner' will emerge on Nico, as the uk, aussie and other forums have. There's always a market for those wanting to retain stock electronics.

Whatever standalone u go with, have somebody on hand familiar with tuning it or get ready for more frustration and a helluva learning curve.

I believe microtech retains all your factory sensors. Seen great results on many street cars with it. Fastest ET (11.1sec) on the forum is microtech tuned at only 17psi. Certainly gets the job done.

I live amongst some 'SDS gearheads' and seen the ups and downs. Dee perhaps the most headache-free route.

I'll probably try one of the less expensive standalones (holley, EMS, Mgsqt+EDIS) if I go that route, as I'd like to learn tuning myself.

boost_boy,I wonder whose factory electronics/loom ages worst, nissan or mitsu -lol. DSM with their dying ecu (caps) and our lovely mitsu CAS. Nissan wiring probably gets harder/brittle and corrodes more tho.

[r34 gtr]

there are plenty of people on here who could burn me a chip. ive just had enough of this car's terrible engine control electronics.

i have a z32 maf and have it tuned for it.

dee is more than capable of making my car run like a swiss watch. he has been doing this longer than anyone else (and ive been at it for 5 years!)

and finally, my harnes is in pretty good shape. just a few chipped connectors because i was impatient getting them off.

i dont mean to flame or anything, i just have a pretty good idea of whats best for the car, having been here longer than most.

edit: p.s. - the safcII sucks! ahahaha! die apexi! seriously, i can only adjust fuel, and its in 1200rpm increments!
