Untamed Z

Looking for a DFI file to try to get a baseline. It's the original DFI unit ( I guess 6.0 or 6.32) The part # is 74040. Here's my engine mods: 350 L98 9.8 CR

Canfield 200 CC Alum. heads
TPIS Mini-Ram
TPIS ZZ-409 Cam .525 lift 226 dur. 288 adv. 112 LSA
26# Accel injectors
Hooker Super Comp. headers
48 MM TB (for now)
MSD 6AL

I guess I'll be running 48-52 PSI fuel pressure.

If anyone can post a link or email me, I'd sure appreciate it.

Untamed Z…Cal-Map 6.32 has an excellent tool in the UTILITIES section under GLOBAL, you can create a base fuel map that will be sufficient for your needs. It will ask for parameters such as how many cylinders, what lb. injectors, fuel pressure, peak HP, peak torque, peak HP RPM, peak torque RPM, etc. Be honest with the numbers you input and it will give you a map to run as a base line. There is no need borrow and files files. You can’t get to the UTILITIES section offline, so you need to make sure you have the DFI powered up, do not start the motor.
I’ve used this utility for all my maps and it comes very close to what I need. From there I go to the track and fine tune. If you need a copy of Cal-Map 6.32, just email me and let me know.
If you bought this DFI used, make sure you go over the DFI configuration under CONFIGURE ECU in the GLOBAL section. If the DFI isn’t configured for you application, you will have a b*tch of a time trying to tune anything. Hope this helps.

Thanks Fast. That's twice you've helped me now. My plug-n-play should be here tomorrow, so I should have the DFI in the Z by tomorrow night. As far as plugging in the HP & TQ numbers, I guess I'll start out around 375 HP and 400 TQ. Am I pretty close or do you think I may be a little optimistic?

Hmmm...good question. I would talk to your engine builder for an estimate of your HP and torque figures. Since you're using the TPIS intake and cam, give one of their techs a call. They should be able to help you. With what you have though, I don't see why your motor combination won't the seeing your estimated 375hp and 400tq estimation at the flywheel if it was put together by a good engine builder.
What I like to do is make up two fuel maps with the DFI utility tool. One on the low end of my power expectation and one on the high end of my expectation. One kewl thing I like about the Accel DFI is that the entire fuel map can be raised or lowered in percentages on the fly.

Hey Fast Life,

In this utility tool, will it allow you to estimate a bar or psi for the forced induction motors or will I be screwed in that aspect. I wish I would have known about that tool along time ago. I just started programming on the fly. I didn't do too bad but I know it could have been alot better. I was thinking that I was going to have to go to the new 7.0 version in order to get that kind of utility. I don't recall it saying anything about it in the book. Anyway how bout that forced induction ability. Thanks.

LIL QIK…the utility tool generates a ballpark fuel map based on the injectors you are using and the power output of your engine combination. It does not take into account whether or not you are using 1,2, or 3 BAR MAP sensors. It is in the ECU CONFIGURATION section that will prompt you for which BAR MAP sensor you are using and will reflect this when you enter the BASE FUEL MAP section of CAL-MAP. Again…the utility tool in CAL-MAP only generates a “ballpark” estimation of a fuel map for you to use. You will still have to fine-tune the fuel map for your engine combination. It shouldn't really matter though, because it is more in the timing matrix whether you are using forced induction or not. With forced induction, your timing should gradually retard at higher RPM speeds. The timing matrix you will have to tune that for your particular application.
As far as the Accel DFI 6.0 box being able to work with forced induction applications, we already know that it can what with the many supercharged Camaro users and turbo Buick users that have applied them to their engine combinations. It may not be as sophisticated as the newer DFI 7.0, but it works and there are many out there that know how to tune them. CAL-MAP 6.32 was the last version Accel released for the DFI 6.0 box. I believe the DFI training manual stopped with version 6.0, so documentation on the UTILITY function was not covered since it came out in version 6.32. Wish I could have been more help to you.

You were actually alot of help. Thanks

Untamed Z - I have some programs that will get you in the ballpark. Where in Illinois are you from?

Untamed Z

HiTech... I live in the Decatur area. Basically what I'm looking for is a fuel chart that will be fairly close for my combo. I realize that it will need tweaked for my application. Like you said, something to get me in the ballpark. You can email me back or post it on here..whatever works best for you.

I'll send it over this evening. Let me know how it works.

Untamed Z

HiTech, I'm putting on the DFI unit after work today. I could sure use that file you have. Thanks.

Sorry, I got tied up at work until late and my wife was working on the computer last night. You will have it this evening.

Now what to do to find out the base Ignition timing map? I'm not running a knock sensor on my configuration. I'm running an LT1 with ported aluminum heads, and since the LT1 has reverse cooling, my CR is around 10.8 pretty safely. Where can I start with some Ignition timing maps for such CR. The cam I have is a CCXE 230/236 .544"/.556" at 112 LSA, If that has anything to so with it. I also know that LT1's can run a little more advanced without detonation than L98 motors.

Previous to the cam I'm using presently, had the same cam as yours in my 383. My compression ratio is 11.5-1. Under full throttle, I am running 37 degs total timing in by 3800 rpm and pulling out 1 deg at 6200. The intake used is a MiniRam which is very similar to your LT1. Someone is going to balk at my total timing but that's where the car runs best!

Hey HiTech5 do you think you could send me a copy of those files too. I would greatly appreciate it. I am in the Mattoon/ Charleston area of IL. I have a 383 with a superram in my 88 gta (hence my name). No hurry I' m still trying to figure out how to keep all my gauges and stuff working like stock when i put the dfi in. Would just like some strong starting points to go from. Thanks.

88GTA383 - I cannot tell by your post if you have a DFI yet or not. I have a 1986 TA with DFI. I interfaced the DFI computer with the factory harness via an interface harness from Dan White Racing. All of my guages work the same as stock. Email me some info on your combination. I have a 383 SuperRam program but I will need to know cam specs, heads etc.

HiTech5- I emailed you my info on my 383 did you get it , just checking if not Ill just give it to you on here.

Dude - Your email address has me a little concerned!

lol , my name is Damien and my friends came up with the nickname. Do you have anything close to my combination to get me started. Thanks.

Hey what's up Hitec I need help with tuning my DFI Accell #740465 with my profile listed below would you have a program for me my car is running very rich right now (10.9) and I'm really new to DFI tuning and would appreciate any tips also if needed I can email you my Dyno sheet.

Thanks,

What cam are you using?
