Thread: Ignition Timing Tuning Questions.

Random Blabbering:
I have the AEM EMS and the base map runs good for now.

I will be tuning my A/F ratio's first then I need to do my ignition timing. With this being said could someone who really knows dyno tuning give me some pointers. (I fully understand this is a street tune and there are thousands of variables, but like everyone I would like to give it a shot).

I have a fast reading datalogged egt sensor on cyl 4 to monitor the temperatures.

Questions:
Q1: Now what target temperature am I trying to hit for safe map on 91 octane sr20det t3/t4 turbo, stock block.

Q2: If someone has a picture of a tuned AEM MAP for sr20det stock block pump gas with t3/t4 turbo just so I can compare to see if I am out to lunch. Could you please post this up.

Q3: Do you have any tricks that could help my learning curve IE. you should put in +2 degrees timing before boost hits to help spin up the turbo etc... <-- I just made that up as you can tell.

Thanks,

if this is your first time take to a professional. Poor tuning causes things to go boom. btw I run aem and I can set it up but take it to a pro for tuning.

agreed, start with a PRO... get it running right before you go messing about and hurting your motor

Which base map did you use?

I am using the AEM base map and changed the injectors.

also you really can't tune with egt numbers unless you read all four cylinders.

yes... which one

You didn't help answer my questions, what if I had two spare motors and I am very interested in becoming a pro at tuning and I need to start somewhere, would you respond like you did, well then what EGT temp do you tune for?

S13 SR20DET
MAP SENSOR
INTAKE AIR SENSOR
FMIC etc...
550cc

That one. I am at work and don't have the map # handy.

Thanks,
Andrew

Is this a RWD or FWD SR20?
