timing recomendations log attached

infini_IV · Oct 25, 2009, 02:14 PM

im using a stock 90550001 rom with 2byte load enabled and getting some high knock counts attached. weirdly my timing figures in the log dont match those in the high octane ignition map, anyone care to offer any advice or recomendations.

im logging at 15625 baud as apposed to the 62500 others recomend as at this fast baud rate the signals go crazy

I dont have a way to look at the log on this computer, but...Your timing probably isn't matching because it is being reduced by the ecu seeing the knock. Reduce the timing in the areas with knock and smooth out the entire map.

too lean m8 also e mail sent

First thing that I see is that your TPS isn't set correctly. Looks like somebody has been wrenching on the car that doesen't have a full grasp of things.

Secondly your coming in with fairly aggressive timing, but the car takes it. At about 4500rpm's the car starts to complain.

Fix your TPS, check for boost leaks, and reduce timing.

What grade of fuel? Last time I was in Christchurch futzing about I know I looked to see what was available but I have already forgotten.

when i was travelling there recently they had U.S., 93 octane ( i believe it was 98 similar to the uk and european countries) but the O.P. should confirm

looks like your running lean in that log. 13.3 AFR at 4k is LEAN

Fuel type and boost level?

Your fuel map needs some serious work, richen it up a full point to start!

Def agree with 0xDEAD, your TPS isn't set probably. I bet your cable is really lose and so it doesn't open it all the way at full throttle.

fuel is 98 RON are all ralliart 90550001 mapped this lean? as far as i know its a standard rom

could it be a fuel pump issue? car is mostly stock with 3' catback and tubular manifold

I think that is the Lean Spool still functioning.

Possibly unless its been tuned. I agree with JB thats lean spool is more then likely still enabled. Have you messed with the fuel map then?

infini_IV · Oct 25, 2009, 11:12 PM

no it hasnt been tuned its a stock ralliart rom so lean spool will still be enabled

whats the general thoughts on stock pump limit

JohnBradley · Oct 25, 2009, 11:34 PM

Stock Evo 7/8 pump will be done about 21-22psi generally, but you wont see that till up in the rev range (5500+).

The Ralliart roms are too lean IMO during spool up.

this might be a bit off topic, but when I try to open your log file, it opens in excel, which is fine, but it opens all the data in just 1 cell, making it impossible to read/interpret the data, does anyone know how I can solve this problem? thank you..
