Looking to push around 15lbs of bosst.

I search and search...everything I find has expired download links or it isn't similar enough. We're tuning on a dyno right now, but it would be nice to have a map to cheat off of for the rough tune.

 

I tuned a car very similar to that except it was sequential, at 14 psi. I don't have the map but all I've gotta say is add some fuel up top and fix the split (10-12 is good). Make sure the injectors are set up correctly and are staging properly. It's pretty straightforward on a car with stock primary injectors running 15psi or less.

make sure the MAP sensor is set up right. For the GM 3 bar I use scale 6630 offset 0, per Banzai Racing's recommendations.

EDIT: I'll upload a MAP that is similar to what I was running on that FD, I'll upload it for your reference at least. You can put this in to the car and see what it does, obviously I'm not responsible for what happens. The timing and driveability stuff should be pretty good, but the fuel under WOT is anybody's guess. I richened up BaseMod map that comes in the later Power FC's. You can use the FC-Edit "Compare" feature to see what I did (compare it to the BaseMod map).

 

great. thanks, we'll check it out.

 

with your map, or the one we were working on, the car is really leaning out and breaking up into boost, even after cranking up the injector map. havent been able to make a pull past .16bar so far...

perhaps something is wrong with the injectors? they are brand new with a flow test though...

 

Do you have ignition upgrades? It is well known that the FD ignition system sucks when you get to a certain power level. FC leading coil plus HKS twin power is a proven combination. On my FC I used to get breakup over 12psi, when I put in a Twin power I could pull it to 21 with no breakup. We had similar breakup problems on that FD, even running stock FD coils + Crane HI-6 on the leading. Also, did you rewire the fuel pump? If it doesn't get proper voltage it will never flow. I have a Supra TT pump in my FC and it would lean out due to a fuel pressure drop. A rewire solved that.

that map is practically maxed out fuel-wise (INJ map is near 149) up top unless you perform a recalc , which zero's out the INJ map. I did not recalc because the car i used it on didn't need it. The AFR's were fine, but it was a sequential car and didn't have the flow improvements of a "rich man's" non sequential. And remember, that map is not too far off from the basemod map. So if it's lean on that map i posted, it would have probably been worse if you just tried making pulls untuned... And you do have a GM MAP sensor right, not the Apex'i or something else?

Post datalogs of your pulls. Save the files and upload them, there's nothing we can do without those logs. Is your wideband hooked into your datalogit? Did you verify that your datalogit and your wideband display agree? You need to do that. We need as much information as possible.

 

arghx - i think you're right. at this point im suspecting electrical issues.

we went back to my old map after trying yours, but tweaked it a little more. the map is pretty much maxed out at the top end. we did a pull to almost redline and the car made 273 horse. no detonation, and the motor seemed fine, but it smelled wicked rich.

we also tried a different wideband and it was giving us much richer readings.

i think the problem is ignition. the injectors seem to be doing their job and dumping plenty of fuel, but it's just not burning up enough. i checked the plugs and they weren't foul, but pretty dirty. i just went a head and ordered an HKS twin power, and i think we're going to re-wire the fuel pump today. earlier this week i noticed the car's check battery light was occasionally lighting up, so i think we have a loose connection somewhere...

we're going to do the fuel pump wiring and try to shake out the electrical issues today.

 

hang in there, it can get pretty frustrating when you get the car semi-tuned, then you have to fix something and retune again. When I rewired my fuel pump I had to retune almost the entire portion of the map in boost because the car didn't need as much injector duty cycle to maintain a given AFR.

like I said though, if you can eventually get some datalogs posted up we can help you more.

 

the twin power & the relay for the fuel pump wont come until later this week...

today we're just going to tune it so it's streetable at stock boost.

i'll see if i can upload my datalogs after we put it back on the dyno in just a little bit...

 

what plugs are you running? the HKS twin power is not recommended for non-resistor plugs, just so you know (stock BUR9EQ are resistor, B10EGV is not).

 

stock plugs.

after all this **** with the 1300cc's i finally decided to cave and order a whole kit with 1600cc's.

we were worried that we might be maxing out the 1300's at the level we're aiming for anyway, and i didnt feel like ******* around with the 1300's anymore so i just ordered the "Extreme Fuel Kit" from rx7store. should be here by the end of the week.

if the fuel kit, pump rewire, & twin power don't take care of the lean issue, then i dont know what will.

 

have you verified all your sensors are in spec, like the TPS? When you say stock plugs, you are running 4 trailing plugs right (9's) ?

Next time you do pulls, I would record "Advanced" under the monitor window. Then put a chart together of:

RPM
Boost (I actually prefer PIM as it is in the same units as the fuel map itself)
TPS voltage
InjFrPr
InjFrSc
Injector duty cycle (you would need to log BASIC if you want to chart this)
Wideband AFR

In order to make it easier to read and interpret, I would probably split that into 3 different graphs , with RPM, boost, and wideband on one, the two injector readings (and maybe duty cycle) on another, and TPS voltage on its own seperate graph. Then set each graph to its own appropriate scale (like 0 - 5 for the TPS, etc).

From there you can clearly see if your injectors are staging decently. You can check to see if your Accel enrichments settings are good--as the rate of change of throttle voltage increases (try to remember anything you can about derivatives if you ever took calculus, basic calculus concepts help a lot with datalog analysis), you should see InjFrPr spike and the AFR's go a bit rich to compensate for the throttle movement. You can use the "map trace" and "ghost" features so that as you move the slider through the datalog, you can see on your fuel map which cell it falls into. Map watch works too but I find it harder to use when I'm tracing through logs.

This data analysis strategy helped me fix a lot of hesitations on my car, which has 720/1600.
