With an LCA of 110 and with the duration that you are running, 1000 at idle sounds about right. You could probably get it a little lower but you may have vacuum issues. You may have a few low load/low rpm bugs too. You should see good high rpm performance.

Ya that is what I am seeing now when it comes to driving from a stopped position. I get bad bucking.

So I removed the ACT sensor and it had a little bit of gas on the tip of it. I stuck my finger in the hole and rubbed on the side of the intake track and it was wet with a little bit of gas too. I think this is what is causing the high temps. I think my injector timing is off and it is shooting gas too early. So with the overlap and the early tinjector timing....hot gas is being pushed back up by the exhaust stroke and coating the sensor. So theoretically if I were to increase the injector timing to start the pulse after the exhaust closes this should fix the high temps. Will that work?

Correct me if I am wrong here...when adjusting exh lash,intake to max lift...then past to about half way closed (2/3 closed varies a bit depending on who's talking) ??

I always wait until the intake valve is almost all the way closed then I adjust the exhaust with 1/2 turn preload.

I adjust the intake valve when the exhaust just barely begins to open.....again with 1/2 turn preload.

I was hinting at the fact that he is using a 30# cald maf which I can only assume is a pro m bullet 75mm which also would be undersized for the op's combo and 62# injectors. I am doubting that the maf xfer input into the tune is correct for his combinaton.

Where did this tune come from? I see too many things I dont like and I would consider starting from scratch. We can help if you are interested. Forget about the valve adjustment for now.

I looked at the tune too and there are lots of things messed up. Your MAF transfer is all jacked up. Not sure why you are adding 15* of timing at idle and you have your CID messed up. I agree with Ed. Start over. Too many setting messed up to diagnose your issues.

Those are the same things that jumped out at me right away. Not to mention The injector slopes set to 35. We need to determine what maf is installed and explore the possibilty of replacing it; we can work with it for now though.

I'm new to this whole thing and was going off stuff I have read so bare with me.

CID is 204 injectors around 30ish and maf all crazy because I halved those because I though I was not suppposed to have over 2k on the maf. So I scaled everything by half. I would greatly apreciate a little guidance. I can give you all the information needed for a basic start point.

I went back to a stock A9L tune and changed the following:

1. Changed CID to 408
2. Changed injectors high/low to 62
3. Changed injector offset to the 60# setting from EA
4. Input the 30# MAF transfer from EA
5. Input injector timing that was calculated from EA based off my cam and rocker ratio.
6. I put 1.00 for lambda values all throught for base OL to tune the MAF.
7. I ran the car and adjusted the MAF based off of lambda values recorded by BE and imputed into EA

Is this a correct approach or am I way off. I really apreciate the help you guys are giving me so far.

I was under the impresssion it does not matter what the MAF was tuned to when you bought it as long as the MAF transfer is correct. The MAF I have is the Pro-M 30# MAF purchased from Massflo efi. Website is... www.massfloefi.com/replacement-add-on-p ... meter.html

This is the correct approach but there are other issues. Forget about the injector timing for now and use the stock a9l settings. Remove the globas 15 degree spark adder at closed throttle and you should have your tune set to run the sealevel table only for spark. spark adders will still be in effect. Post your new tune and I ll make some changes to help you out.

This is not a pro-m meter. This is a completely different set up. If this is the set up you are using you will not be able to use the maf curve from EA. You will need the flow data sheet that came with your mass flo unit.

I had one of these meters before and it broke. Sent it to Pro-M and they sent me a replacement that was exactly the same with a sticker on it that says pro-m calibrated for 30 lbs.

I'm not sure what you mean by this. You are on the right track but all you need to do it set Z_OLSW to force OL (which you did in the tune you posted earlier). Then clear your KAMRFs using Z_KAMCLR (be sure to set it back to normal after you clear them). Then set Z_ADPSW to disable (again you did this in your earlier tune). Then just log your driving for a while. I usually try to get in a good 20 mile drive varying the driving style. Your base OL table appeared to be unchanged in your earlier tune. You can leave it that way or you can change it (I would change it.) I usually replace all the the values under 65% load with 14.65. Then as you get above 65%, you can start richening it up until you are at about 12.6 at WOT and loads above 80%.

After you do that, run the log through EA. Be sure you have the filters set to eliminate accel enrichment and transient fuel. Also be sure you have it set to only use OL. Once you do that two or three times, you should get your MAF dialed in pretty good. Make sure your new MAF curve is a smooth curve. If you look at the one you posted in you early tune, it was far from smooth and that will give you all kinds of headaches. You will probably max the ProM out at WOT so you may need to look at getting a new one.

I am gonna go out on a limb and say that massflo is using pro-m to flowbench their units. You should be able to contact pro-m or mass flo to have them email or fax you the flow data sheet for your unit.

this is 100% correct. Use the flow sheet provided with the maf and you are done. My sheet was so on I haven't even touched my maf transfer tables.

Attached is my updated tune for the guys wanting to look at it. I took the recommendations from above and basically changed only what I was told from a stock A9L tune. The maf transfer is what I am using now seeing as it is dialed in close. I will add the transfer function from my calibration sheet once I get Pro-M to send me it. Is this a good starting point? Is there any changes I should make before driving for a datalog?

Thanks again for the help.

Give this a try. I doubt the maf xfer is going to be correct and probably be rich but it is from a pmas 75mm maf. Its a start.You will need to dial in the fuel and idle. Hopefully you are able to get the maf xfer for your massflo efi unit and we can go from there. I didnt touch the timing.

I ran the car and it was super lean with lambdas of 1.20 ish. I figured it might just because the maf curve was lower than what I have been seeing. I inputed my maf curve I had in the tune I posted before the last one and the lambdas were around .95. It was also runnig rough and would barely idle which was expected. The awesome thing to note was my act's stayed around 140 so much better than before. What would be my next step after dialing in the fuel? Seriously thank you for your help.

So I went back and put in the transfer function from the tweecer yahoo group that is for a 30# calibrated maf that looked like mine. It was pretty much the one you put in that tune EDS50. It was super lean too. So I went ahead and started tuning the injectors. I went from 62 down to 56 in both the high and low and that seems to get the lambdas close if not right on 1. Does that sound right? The loads are a lot lower now than they were but the ACT is still hot. I am guessing it has to do with the cam overlap because when I rev it up the temps actually drop. It still runs a little rough though. Should i continue tuning the fuel and work on the idle? When should I start working on timing? Would the engine running a little rough have to do with the timing? Thanks for the help as always you guys are awesome.

Are you sure you don't have a retarded cam getting exhaust reverting back into the intake?

If I was tuning your car, I would set the slopes both to 62. I would then take the MAF curve and multiply the whole curve by whatever % you are lean. That will get you pretty close at idle and low load. You need to either adjust the MAF curve or the injectors......not both....at least not at the same time. You will just chase your tail. The ACTs dropping when you rev it is normal. You are simply taking in more air so it is cooling off the intake track.

So, my advice is just set the injector slopes equal to each other and then do your tuning via the MAF curve. If you are lean then find out what percentage you are lean by and then use EA to multiply the curve by that amount and then see where you are at. Its very likely that you will need to make more changes in the curve at the higher flows but you can do that later when you start tuning WOT.
