did you change the oil? how was the oil?

 

What error are you getting and when?

 

Gman,

Is your EU running absolute timing or +/- whatever the stock computer chooses to run?

 

WOW, I like to have a reliable car.... makes me think twice about getting FI

 

i thought you can't run absolute timing until greddy releases their new firmware? Thought you can only do target A/F for now?

 

Oil was fine. I change the oil every 2000-2500 miles...at the most 3000 miles.

I am using the TS Greddy flash for the timing. EU timing maps are set to zero and the EU was controlling fuel.

 

No error, but when I go to the data log field it does not highlight any of the options in that menu.

 

I am not too familiar with the TS reflash but is the timing retard on it good enough for the higher boost levels? The reflash might be your answer, I am just not crazy about it as I have seen mixed results on NA and with FI there is no room for error.

It might be the COM port for the cable.

 

I was just thinking the same thing. I thought it was only good for 8-9psi of boost.

 

yeah with that much power and that much at stake with the engine i'd probably opt to adjust the timing using the EU, even if it is the +/- method

 

That's just because no one has come up with a larger MAF setup for the ECU to read from. Not much to do with A/F and ignition timing.


It seems like everyone who has a reflash ends up having trouble with it at some point...350zdcalb kept thinking his reflash was causing his issues with the eManage (I believe he went back to stock on the reflash and has the EU controlling it now...and coincedentally isn't having ECU problems anymore).

I think Sharif is at SEMA this week, George, have you talked to him about this?

 

That is right the MAF maxes out and the point it maxes out probably coincides with 8-9 psi, so it limits how high you can adjust timing and fuel. So Jorge going up to 12 psi was probably 3-4 degrees too high from where it should have been. So it is a matter of the voltage that the MAF reads which right now maxes out at 5V and finding a way to read higher and the ECU dealing with the higher voltage, probably not as simple as it sounds or it would have been done by now.

 

hence why MAP based tuning is the only way to fly MAF for everything up to zero psi, map for everything over. No voltage clamping to deal with, no MAF restriction either

Otherwise, its alot of reinventing the wheel finding and fitting larger MAF's, remaking intakes, sorting out the wiring, scaling the voltages, etc etc.

 

so how did the warranty issue with sgp turn out are they gonna cover anything?

 

Brandon,

I have told Sharif about this a while back... but I already had a larger 4" diamtere MAF housing fabricated. The Z maf plugs right in. Just haven't had the chance to make the piece after that. If you guys want to play with it, let me know, I can send it over. I won't be able to play with it til at least early December.

 

Will the warranty still apply if it's determined the timing caused it to go?

 

ok, speaking about all this MAF max out issue, makes me wonder, what happens when boosting higher than 9psi, say about 12? and does the Unichip take that into account and compensate?

 

1 year warranty against "DEFECTS"

 

It doesn't limit how much you can adjust the timing. You could run 1 degree of total timing if you wanted to via the reflash(even though the car might not run). The problem with a reflash is the maf and hitting the voltage checkpoint and going into limp mode. Jorge was using the Maf for low voltage part throttle and then it went to Map to add some IPW back in. You can use a flash in conjunction with the emanage and many people are doing this so that all the timing maps on the ecu match in all positions(see ecu stabilization thread). 8-9 psi is the max for the stock fuel system and also the maf. That is why the flashes are for that. Not the reasons you speak of.

 

Doesn't the Unichip have an input for the boost? If so then it is not an issue. I have to admit I have not checked one out.

Like with my setup I run the emanage using MAP so no concerns over the MAF maxing out.
