I also posted this on PGMFI.org and am getting some help but it's much less active than HT so I figured I'd post here too.

So I'm pretty sure I grenaded the existing tune in my car and I need to start from scratch to try and get it running again. (I'm going to be using Crome)

I need a base map for an Integra LS with a P06 ECU. The car has a T3/T4 Ebay turbo (It's held up for 3 years with no issues) with DSM Blue Top injectors and runs at 8psi. I'm just going to AFR tune it and leave the ignition somewhat conservative. I know Xenocron has quite a few basemaps but I didn't see anything that was too close so I figured one of you guys might have something laying around that I might be able to use.

After doing some more searching, I missed that Xenocron does in fact have 2 that are somewhat close.

B18b, 450cc injectors, SC34 Turbo, 7psi tuned, timing untouched...bleh

b18b1 T3 super60 .48 hotside 7PSi tune, 11.3 in boost, 12.5-12 before boost, 14.70 everywhere else, Needs a little touch up in boost portion, .75 degreee retard per Lb. timing untouched

Which do you think would be best to start with?

This is really my first time messing with this stuff so a lot of it is brand new to me. I'm kind of nervous about messing with the ignition timing but I can handle adjusting the fuel map.

MrDomino

My biggest thing is trying to figure out all of the fuel stuff. I'm thinking of using the second map to start. It says that the timing was retarded 0.75 degree per lb of boost. I may up this to 1.00 degree to be safe but when I opened it in Crome the option is not selected.

Also under the fuel tools it says the engine size is 1.6L? Shouldn't it be 1797cc?

what tuning software are you using? do you have the hardware to burn chips if needed or an emulator?

MrDomino

I have both an Ostrich and a Burn 2 and a bunch of chips.

i think you should just make your own basemap and then tweak some of the fuel if needed. xenocron has an awesome write-up http://www.xenocron.com/install/CromeGuide.htm

then get it to a tuner for a full tune

MrDomino

I'm going to do all of the Fuel Tuning myself this next week hopefully and then do the ignition in a few months (I'm leaving everything kind of conservative).

Quick question about target AFRs. I know I want 12.0:1 whenever in boost and 14.7:1 whenever I'm idling. What about in between?

Attached in my basemap that I'm going to be using.

MrDomino

How does this look for a target lambda map? I don't know how to convert to AFR so it's in terms of Lambda.

The map was simply created using a b16/ p30 base. The basemap is most likely already setup for the 1.8l in the fuel trim adjustments, so I wouldn't suggest changing anything here. Your best bet is to pull about 1 deg. timing away across the entire map and then just tune your a/f.

id luv to do this myself....lookin at that chart gives me a headache....

MrDomino

Well I figured out how to do everything just by reading forums so you can figure it out that way too.
