anyone with a miniram have these? I want to compare something and have no reference.

 

No one has an sd tuned miniram here?

 

For the VE table look at some LT1 BINs. That intake is very similar to the miniram intake.

The spark table may convey some meaning, however, the chamber shape is different then the L98 heads.

RBob.

 

not using L98 heads, it's a 355/miniram/TFS195cc CNC heads/60lbs injectors/D1SC and I can not get a handle on this thing.

 

How come you don't try code 59? Don't think you even need to repin anything these days from the sounds of it and all you need is to pick up a 3 bar map sensor. If you need a bin to start off with you could use mine since we are probably close in combos.

Anyways here is a copy of a stock LT1 table I found on the net, maybe that can help.

 

What is your combo? I also have a truck w/ a 355/tfs G1s, s&p multiport and it will need a tune also. Code 59 could be a good upgrade for it since it doesn't have EGR and all that. My buddy has a car w/ $59 on it. It does seem a lot easier to tune.

 

Info is in my sig or my vbgarage for something more detailed. Should get you started with the car you mentioned. The code takes a bit to figure out but probably better then 8d in the end for boosted applications.

 

I did some $59 work on my buddies 1LE, it is running that code on a 383/P1SC. The onle with the funky rpm signal and the messed up running with a steady signal off an MSD box (I'm pretty sure the VE maps on that are all moved towards too high rpms because of the false signal input without an MSD)

 

In my opinion, 60lb injectors are way too big for that engine and you'll never get a tune with them as they will be mostly shut down just to run and idle.

 

It runs fine @ idle, they are not too big. I run 60s on my u87 camaro (MAF tune) also

 

If you are thinking 48#hr they would be maxed out. I have a na 383 tune
From Lingenfelter if you would like to look at the ve if that help you do any compare.

 

You would probably know more than I but, IMO 60lb is just too large. 30lb is more reasonable. If it's a blown engine, then it sounds reasonable.

 

See, you just ran your mouth off and didn't even read....

but then, why would a blown engine not have idle issues if they were too large?

 

Well It appears you have all your answers then. I have basically the same setup except MAP and have it tuned with 30lb and I'm not using half of the capacity of those. Bigger is not always better! But do what ever you want. It's your car and you asked for the help. Good luck!

 

You might think bigger is not always better but doesn't mean it's not going to run. 60lbs work fine on a lot of people's cars, it's all in the tune and I find them no harder to tune then my stock ones...

 

Tuned,
I'd like to see that VE to compare it to mine. Mine was shaped with VE Master. How do you shape the VE tables in your tunes? Would be interesting to compare.

 

Tuned, I would sure like to take a look at it.

 

I will post a screen shot of the ve tables later tonight or tomorrow. Im on super slow dialup today . @ 92Z , I have never used tts ve master but have heard it can make some odd spots in the ve. Using the smoothing in tp will help you correct it. I use a spread sheet for correction based off stock ve and adjust from there.

@Twin_turbo , I will email a copy of that file to you. It has a lame encryption Just look at it as a $8d

 

Tuned,
Thanks. Look forward to it. Yes, I noticed the odd spots in the tables. I have had to go in and smooth. I use Tunercat, so no smoothing function. Any chance I could get a copy of the Lingenfelter file? I would like to compare it to a TPIS file I have.

 

I certainly agree that 60lb can work in lots of car/engine combinations. I only contributed my opinion in order to perhaps help someone. I didn't expect to be flamed. In any case, here is the advice I got when I was sizing mine:

An injector can only open and close so fast (1.7 ms is a good minimum injector pulse), called pulse width. If you use very large injectors, your idle pulse widths get very short. This can drastically reduce the mixture ratio control that you have during idle and cruise situations, and lead to very poor driveability and seemingly strange tuning behavior.

Every car is different, but the standard duty cycle seems to be 25 ms (100%). So the bare minimum for idle conditions should be about 7% duty cycle (1.7ms). Typical injector pulse width for an idling engine at normal operating temperature is between 2.5 and 3.5 ms (10-14%).

Here is the formula I was provided with:

When choosing an injector you want to around 80% of the duty cycle, it's easy to figure out your fuel needs as follows..

Lets say for example you are making 400 flywheel HP, most boosted engines run around 0.55 or 0.65 BSFC ( Brake specific fuel consumption) N/A motors run at 0.50.

Take the 400hp x 0.55 lb./hr-hr= 220 lb/hr max flow or at 100% duty cycle.

next divide the 220 by the # of injectors 8 which is 27.5 lb/ hr per cylinder.

now to find an injector that will run at 90% duty cycle, divide the original # by 0.90. 27.88 lb/hr /0.90 =30.61 or 31 lb/hr needed for this motor.

so you would need a 34lb or max of 39lb injector.

some quick #'s

A boosted motor running 400-450hp could run 34lb to a 39lb injector.

same motor making 460-550 could run 42lb to a 47lb injector.

fuel pressure/exhaust temps can also figure into this but basically the tuner will tune the fuel pressure so if the injector is to big it will only flow a specific rate, the problem lies with an injector that is too small, although a 60lb injector on a 300hp motor might also be a problem.

 

Tuned, I will look forward to comparing mine also. I do know that no two modified engines can run the exactly the same VE because of differences in build, gears and weight but it can be useful in a general pattern of how the table is laid out. Thanks.

 

Sent you the .bin twin

 

For what it's worth, here are the VE tables from TPIS for a built 355 with miniram and I think (not sure) 24 lb injectors. This was developed on their engine dyno. TPIS recommends injectors by hp so for a stock 350 under 300hp they use 19 or 22lb. I live few miles from them and this info Jim gave me to use with my setup which I have since changed so haven't used it. Use for comparison only!

 

Hmmm, curious what TPIS is running for power enrichment and AE for that combination....

 

hey brian, do you have the sa tables or anything else from this tune? I would love to take a look at it. as well as any cam, exhaust, etc info you have for it.

 

It’s the 219 cam tune I emailed to you in $8d

 

then you must not have sent the right bin and xdf. because when i open it it doesnt match this thumbnail .

 

If the data is different I have no idea what bin it is. I have so many tunes on my computer . The view in thumbnail is tuner cat.
