Timing advance in 4th gen
Timing advance in 4th gen
Hey guys.. as far as i know there isnt a software made to connect to the 4th gen ECU that allows you to advance timing like the UpRev Cipher program.. I have contacted the ppl that make the blazt setup and they never resonded.. does anyone know if the blazt OR any other software will allow you to advance timing? thanks in advance
No software that I've heard of, but IIRC, you could run larger injectors and have an AFC dial back fuel trim, which, as I understand it, convinces the ECU to advance timing.
Someone more qualified will need to correct me if I'm wrong or follow up with specifics. I couldn't find any of the threads in which I remember having read that...
What about a piggyback like EU?

Like above mentioned, you will need to do some wiring, and use EU, EB, SAFC, etc... the blazt will not change timing, once you turn off the car and turn back on, it goes back to stock setting so dont even try n waste ur time on that. Or like also above mentioned you can indirectly advance timing, I managed to advance about 10 degree's on my n/a 3.0 and gave me a good amount of power, almost 200whp through the auto, there a big thread on it with every ones experience and input on timing and afc's.
the only reason i ask this question was because im running a VI w/3in MAF tuned with a SAFCII/LC1.. I noticed that on the hi throttle graph im taking out a lot of fuel..
nmexmax.. so thats a fully functional programmable ecu? you can directly write to the ECU.. and you say that will be able to adjust timing.. if so thats sooo glorious

Or would you do it the same way you would with the apexi??
thanks for everyones input.. this cleared up a lot of questions for me.. i think im just going to wait for the bikirom boards to go into production.. thats a great leap for the maxima community
I need to clear this up with the following members comments, just for the record and for the sake of not spreading misinformation as well.
I used to think that until the man showed up with this:

Possibly acceleration and time based... anticipate the next firing based on the previous.. it would be a somewhat coarse method and not as finely controlled as using crank inputs though.
I've been wondering about this for a while now with the EB. He's going to come up here end of next week and I will play with the software and a timing light. Then we'll know for sure, one way or t'other.
I wanted to do that the day I first installed it but couldn't due to missing the cable...
(PS did Matt or Neal ever use a timing light, or just a scanner.. because it won't show up on a scanner...)

WEll well well.
Met up with Knight at the track yesterday, brought my timing light to check out the EB on his 5.5 gen. Turns out it can advance timing. I've actually kind of suspected this for a while going back to a certain conversation I had with Greddy technical people during my whole EU saga thing.
Anyways, I had him add in a bunch of timing while I watched the pulley with the light and it does indeed advance. I mentioned above how I think it works - which is a somewhat coarse method - but it does seem to work. I also added some timing in his WOT areas and we saw his times get better on the next pass down the track (he'll have to supply the numbers, I don't have them).

no they said it works in a 5th gen but in a 4th gen its different...the it will advance it for the time you have the car on but once you turn the car off for some reason the ecu retards the timing to normal
The ECU can say whatever it wants, it doesn't 'know' that the timing is being advanced beyond what it wants.
Unless you're referring to another post, you didn't quote anything so I can only rely on assumptions to who you were responding to.
sorry not when you turn the car off but when you disconnect the battery...but i guess i was retarded when i did it. if people have proven that it works then i guess it does but when i personally tried it, it didnt work for me.

Midrange timing advance will give great results as well
