I'm posting this thread in the FI section because this seems to be where most of the Megatune guys hang out. Mods can relocate it if you'd like.

I am VERY new to Megatune and tuning in general. I let my shop get all the basic tuning done for me but I know my car can be tuned a LOT better than it is now. I just wanted a few of you guys to take a look at my current settings and let me know what I can try tweaking or if there is anything blatantly wrong with my tune. Thanks in advance!

My engine mods are as follows:
8.5-1 pistons (20 over)
210 degree cams

stock injectors
stock 1994 distributor
Maf removed, replaced with velocity sensor

Current problems:
1. I need to press the gas to get the car to start.
2. I need to keep pressing the gas lightly until the car is warm enough to (hopefully) idle.
3. I have a very rough/inconsistent idle. Sometimes it's perfect and then later that day it won't stay running on its own. I currently have it idling at 1150-1300 rpm depending on the day. I adjust the idle mainly by turning the IAC valve in the engine bay until the car will stay running on its own.
4. I am not really sure what normal operating temp. is for the KLDE. Mine doesn't get hotter than 203F and it usually stays in the 190's.

Here's the tune I am using now.

Engine constants.

Fuel VE table

Spark table

Exhaust Gas settings

THANKS FOR ANY HELP!!!

Cold start enrichment settings? I would post them up for people to see. As well as what the temp is like. Alot of the time for standalones a tuner will keep the car for a few days and play around with with the cold start settings in different temps. I was lucky that Radar's base map (who comes from Florida) has very similar climate to Sydney so ive never had that issue.

Also probablly what temperature are you starting at.?

I had one point in time where my car runs great in 80 degree weather, but wouldnt start to save my life when its cool out. I had to change the afterstart enrichments as Turk suggested.

As far as the crancking and having to press gas, same thing goes. Look at the temperature, and tweak the value a bit to supply more gas at crank per the temp.
