It's time to call out Affordable Fuel Injection, Fuel Injection Connection, and Street & Performance!
I've dealt with people who all bought systems that came with 6 cylinder memcals, and they couldn't figure out why it just wasn't running right. As soon as I got them the right memcal with the correct Electronic Spark Control unit there vehicles starting running much better.
So, today I did three Datamaster datalogs:
#1 http://scotthansen.net/stockfuelmap.uni
#2 http://scotthansen.net/modifiedjeep.uni
#3 http://scotthansen.net/6cylindermemcal.uni
I can tell you that when running the 6 cylinder it ran terrible. It bucked and stumbled in open loop, and when it went closed it ran a little better, but still wasn't right.
I downloaded the http://scotthansen.net/6cylindermemcal.bin and noticed it was heavily modified in an attempt to try and make it function. If you were to watch the datalogs there's really no smoking gun, but when you examine the bin file it becomes apparent what they've tried to do.
This is the chip I used from Fuel Injection Connection:

The statement that it can't be piggybacked means that they've used a the wrong memcal. If it was from a TPI car it could easily be piggybacked. I found this out when sending people adapters that bought the other two mentioned. They pulled codes 41 right from the start.
It needed to be said. No one should have to spend big money, and not have it run right.

Ok, Are you bitching and complaining about a vendor or writing a tech review?! If you are BITCHING then take it to the right forum!!!

Sounds like a bitch-fest to me!

Besides, I have installed 5 or 6 Affordable units and as long as order the right options on the harness, it is perfect. I have only had one problem with Affordable and it was a bad chip. But it was replaced super fast and their customer support is second to none!!

OMG!!! You've just been lucky then. AFI has by far the WORST customer support I've ever dealt with.:shaking:

No complaints, but rather stating facts!
I guy I know bought a $2000 TPI system from them and they used a memcal with an incompatible ESC unit. To me, it's just not right to sell substandard items. These guys are searching for ghosts that don't exist, and sending the memcal back for re-programming.
I spent 4 hours of my time to create this in hopes of shaming them into doing the right thing!

Its been a while but ive never had a problem from street and perf..Other than trying to get non bling brackets and such..Ive build a few street rods when i had my shop and the guy mark down there was very helpful..

Other than pcm for less ive never gotten anything from fi vendors..I usually 99% of the time modify the factory harnesses myself..Mark at S&P did do an LT5 harness for me since he had one close to him..

I have heard of problems with affordable when at the track or at street rod shows.

OMG!!! You've just been lucky then. AFI has by far the WORST customer support I've ever dealt with.:shaking:

Maybe it's the way you talk to them. I have talked with Jason at AFI for hours and not just about his harnesses or parts, just bullshitting.... he is very smart and helpful. Always figured out the answer to my questions quick fast and in a hurry.

Looks to me like a bitchfest starting in the wrong forum.

Here's the bin file AFI used in a 6 cylinder that ran the same way.
http://scotthansen.net/AFIchip.bin
Download, and burn it into a 6 cylinder memcal and prove me wrong?
it's for a 383, Auto, with 26 lb. injectors. I threw it in the garbage, so that should tell you it's value.

That has nothing to do with the fact that you are bagging on Vendors in a vechile specific forum. You got a problem with a vendor TAKE IT TO THE RIGHT PLACE!! Slapnut


Try here, I bet it's welcome there. http://pirate4x4.com/forum/forumdisplay.php?f=68

Sorry, but I believe programming and datalogging of TPI to be tech. Maybe you should report the post, and let the moderators make this decision if you feel so strongly about it?

Then put more tech in this tread and less bitching that they cost too much and are not programmed to your liking.

stfu tard, not only is this CHEVY specific beacuase 99% of tpi and efi rigs are running stock hardware based chevy systems but this will also serve to aid others when they search to figure out why thier system aint right without have it turn into a 6mo long back and forth with the vendor.

the only one bitching here is YOU!! now cup your nuts and gtfo.

Sounds like a bitch-fest to me!



Bullshit!
This is not only tech...but necessary tech at that.
More and more of us are running EFI. So that means there are more and more "experts" pointing guys in the wrong direction.
If this thread only helps one of us, it was still worth posting.

No complaints, but rather stating facts!

SO POST SOME FAWKING TECH!!! You said yourself that you created this in hopes of shaming "them"......


Right from the get go you didnt intend on "schooling" us, you wanted to shame "them" and call them out on their shit products.

If you are so smart with all of this, why dont you build your own systems and harnesses and have them PERFECT!

I think I smell a Troll here?

The real problem here is that about 2 or 3 years ago GM switched to a one time programmable chip, and really increased the cost of the memcals. Some use adapters, but I figured out a way to remove that chip and solder in a flash chip.
Gone are the days of buying them for $40 or $50 bucks as some of you know!
Warning! You can no longer buy memcals from GM for the Mass Air TPI's. And my GM connection has told there's not many Speed Density ones left.
I actually get calls from them for re-programming of Corvette models they no longer support.
I've quit selling memcals outright, because it just got to be to much.
The 6 cylinder thing has really bugged me. A guy in Kansas spent 4 months trying to get a truck running right. He bought an entire system from Street & Performance, and turns out it was a 6 cylinder memcal. He called them on it, and they sent him the right one. What about the time he spent chasing a problem he would have never found.
If you were to look at the bin I posted originally you would see the following.
They turned down the block learn memory, so the ecm is no longer capable of the learn function. The entire fuel map was reworked so that it wouldn't run overly rich. So if you were to run the datalog I posted you would see there suppossed stock chip ran lean in my slightly pumped SBC.

Maybe it's the way you talk to them.

That there is a funny statement. If you knew 1/2 the story you'd never do business with AFI again....

This is a bump for the guy on the east coast I'm dealing with right now who bought an entirely new First unit with a 6 cylinder memcal. WTF, do these guys even try and drive these things?

I have the Affordable Fuel Injection set up on my rig, it is a 350ci. 290hp GM crate motor, I can't get it to run good, it runs rich and the idle changes all the time.I just change the plugs in it yesterday and they are black. I live about 20min from the guy who owns Affordable Fuel Injection, so i went to talk to him about it and he said that i needed to change the cam because they can not get that motor to run right because of the cam and only 8.5:1 compression.

So what do you think? I will send a PM also, Thanks

You can start by buying a 16163139 memcal from http://www.gmpartsdirect.com. This is a memcal from a 305 TPI Camaro and is half the cost of the famous 16151348 AUJP 350 F-body memcal. Next, you can send it to me, or buy one of the adapters from the guy on E-bay for $75. The guy on Ebay uses a AUJP Broadcast code, and can turn off things like VATS, and EGR, and I believe he's capable of modifying injector flowrates.
The solution here is that you'll now have the correct ESC unit on the memcal, so your timing will be right.
If you need fuel mapping because of cam changes you'll have to find someone like me to modify the VE (volumetric efficiency) tables or you'll have some hesitation from radical table shifts in the block learn memory process.
You can also learn to do this yourself like several members on this board have done. The links page on my webspace provides all the sites to do this on your own. I encourage anyone to do this. I still modify my own programming and try different things to make mine run better.

Here I am tuning a 460 Ford for a guy who's using a TPI 7730 ECM to control his injection unit. I modify his programming and post it to my webspace and he downloads it and burns it himself and sends me another Datamaster datalog for me to review.
http://www.scotthansen.net/tune.jpg
I run Datamaster with the Histogram open. I've clicked on cell 800 rpm and 50 KPA. You can see it was hit 10 times during the log and recorded an average blm of 130. What we want to do is take 130 divided by 128, and then multiply it by 57.8 that we see in the same cell in Tunercat. We can now change this cell to 58.7. The only problem is that it doesn't record all cells, so you must average the remaining cells.
This is how you would tune for yourself. The BLM learn function works great, but the closer to 128 you get the less hesitation occurs.

Mine is a TBI not a TPI, don't know if that matters. once i get the ECS i will answer all the question so that i can get it to run better.

Mr. Willys is just telling it like it is!!! I am the customer on the eastcoast that ordered the complete new FIRST unit and got the 6cyl memcal to be used with a hot 383! Just goes to show you that no matter how much time and money you spend looking for a great product if you don't get a vendor that really cares and wants to do the right thing you end up with problems. After calling and talking to AFI a half dozen times, I am still waiting on the updated chip that they were going to send me. That was about two months ago! I just moved on and found Mr. Willys who has done everything he said he would, when he said he would do it. I think after this week he will have mine running like a top.

I also have a 350 hp 350 with a comp 270 cam that afi tried doing a chip for me. Its so rich with a stock throttle body that my brand new exhaust is black after about 3 hours of wheeling.
