3800 Ron, Mat, LQ1/LS1 MAF owners.....

[Fish]

So far the car is running ok since the LQ1 MAF install. I used the tables ZZP has set on their site.

The PT didnt like all the numbers so it rounded up. I figure Ill have to do some fine tuning with the MAF. Im hoping to get a scan going tomorrow since Im grounded due to the little one and her fever. Along with shitty weather.

Also, there was one thing I forgot. The stock TB had the fitting on the bottom drilled and tapped for another hose. I had zero clue on what to do with this so for a temporary fix and to make sure there was not a vac leak, I plugged it into the N* VAC line which leads nowhere since the TB adapter plate isnt machined in that area. I am going to assume that is a PCV valve function?

Use the stock maf values and tune from there. It's a lot easier, it has about the same curve with a bump around 7K, and you just need to raise the values a tad. If they are using the DHP tables that were going around, you will have a lot of trouble with them.

I kept the stock values saved in a CVS file since the actual stock values are for 98-98 TBs and it was running a 99+ TB with those values.

why dont you guys go speed density

I think tuning the MAF is alot easier than a VE tune. Did you do tuning when you had the GTP?

 

[Fish]

From what I read when I had a HPT, a SD tune would be cake walk. The PT involves a bit more IIRC. People usually go MAF tune, then a VE tune.

actually no, there is a big reason why FI Lsx guys go to speed density, there is a reason why EVO guys with big turbos go SD, there is a reason why My SRT was speed density. There is a reason why your car is slow

yes my car is slow, but its not because I dont speed density tune.

Doesn't work well for a DD with a changing climate. You have to re-tune it all the time. I did a SD tune to mess with it, the MAF is fine on these cars, as long as it isn't an obstruction to airflow.

Umm, yeah, I think Im gonna take Rons advice and throw the stock MAF tables back in. Im either running rich as fuck, or lean as fuck. 999 O2s and 0 KR, or 832 O2s and 5.9* of KR. Depends on when I get on it. Ill be scanning on the way to the dyno day tomorrow. Fucking weather.

our VE tables only go up to something like 4psi too, correct?

That seems not so good for a boosted car....

MAF tuning works fine, and runs better. These things barely start when running speed density, and that's with the table tuned damn near perfect.
