I'd like to get some reviews from forum members that have used these maps before and how reliable they are.
I'm trying to get a database of people who've used these maps so we can share our experiences and improve if we see a pattern (leaning or richening up a mixture or advancing or retarding timing)
While it will still be a temporary tune before getting the car to a dyno, it should prove safer.

Ok so this is the site popular for hosting maps for the PFC.

Hi I am running a slightly modified - David Ieroncig map.

I am running UK tesco 99 fuel.

Mods are decat, airpump removed, Aircon removed, Greddy elbow, Front mount, Non sequential, HKS mushrooms, Standard fueling apart from Fuel pump, now running just about 0.8bar boost.

AFR at top is high 10's, after leaning the fuel slightly at the top, was running low 10's before I tweaked with wideband.

Not got it on rollers yet, but its quick, and would guestimate a conservative 300rwhp.

Max knock count I have seen is 45, and only hits that ever now and again. Generally always getting a knock count of around 30 at low revs/load.

Timing map remains unchanged.

p.s If your running 12's at the top end - I am led to believe you are pushing the limits a bit on a RX7, I am safe at high 10's but you are running lean in the 12's.

There have been threads about this recently.....several of those maps are completely bogus or just plain bad.

RobEvo5

Would agree - Anyone thinking about one of these maps make sure you have a wideband at the very least and proceed with caution. And just because the fueling is good it don't mean to say the timing is right and you are not running way too advanced and detting. So keep a close eye on knock count, and make sure you have some faith in your old knock sensor.

Also these maps do not show the back ground settings like injector lag etc,etc. So what you see on these maps is NOT the full picture.

Detcans are probably a good idea, although I do recall someone saying Detcans are a waste of time on a RX7 as once you hear it, its all too late on a REX. Personally I can't see how you can map without measuring knock activity and fueling but thats another discussion for another day. I have stirred up enough of a hornetts nest for one day

sdminus

There is some pretty random neg splits in some of the timing maps on there. Random is a nice way to put it.

rynberg and robevo5
I agree with your guy's statements
What i'm looking to do is to have a temporary setting until they go to a dyno.

And your guy's comments is exactly what i'm looking for, the criticism on the maps and what we should do to correct it, I don't want to see people using these maps and blowing up more rx7s, me included (I was disappointed and shocked at the AFR levels on the map I used)

RobEVO5, i agree with the the statement about being lean at 12 afr, especially on 91 octane, so later that day i filled it up with some 100 octane and then richened up the mixture where it was lean.

rynberg

A temp setting for the dyno? What are your mods?

RobEvo5

You are more or less running a similar base map to me. So what this does demonstrate is that no 2 cars are a like. You are are/were running lean. I was running way rich on that fuel map. In order to get my AFR into high 10's, I have pulled back the injector % to 95 to get about 15afr on cruise, and also pulled back the fuel cells at the top very slightly, and leaned the idle a little to get 13afr.

My mods are:
Decat, Non Sequential turbos, Stock injectors, Air pump removed, Aircon removed, Rats nest gone,HSK mushrooms,0.8bar boost, Greddy Elbow, Front mount, Fuel pressure gauge but no visible sign of a pressure regulator but might be somewhere that I am missing. So probably stock fueling and certainly stock injectors.

What I would like to see is this bloomberg site or another website created/updated with current maps from users online with a full specification of mods. This would be very useful for allot of people, but the tuners might not liike the idea of this suggestion.

Albeit I am still learning, and have probably embarrassed myself on the odd occassion due to lack of knowledge, but I like playing and learning along the way. To me mapping, and modding the car, is a large part of the fun, and more base maps would help people like me to at least make sure we are heading in the right direction.

Good luck and would be intrerested to here of otheres peoples experiences with these maps, assuming others have been brave enough to try them.

I don't believe I would look at injection maps as anything but a starting point on someone elses map. Fuel will almost always have to be tuned based on the number of different variables (fuel pump, fuel pressure, injectors, rails). So the only real benefit of having a maps section is the ignition timing maps. I think with a few maps for stock, single turbo, seq/non seq, streetported, big streetport/bridge you would have something everyone could use or at least start from, might also want to include octane used. I can post my ignition map for my stock port non-seq car to get it started. Never had a problem except at transition with knock but from what I found it was just driveline noise. I am going to use this map as a start for my single map, depending on if I rescale my map for a 3 bar sensor.

Taking a look at the site I think Chuck's map would be a good starting point for timing maps though I think you could run a bit more timing on the top (15 psi) ~15 deg(though that map is for a small street port, I believe, so maybe its fine). Also I like to ramp the split in a bit more for WOT, though I don't know if it makes a difference in smoothness. I just felt better having a bit more split during boost transition.

I have attached my timings for my non-seq setup. Also is my what will hopefully be full timing map for my single setup. I of course will not be using all that timing at first but eventually that's where I hope to be. Of course if you use them do so with caution.

SPICcnmGT

Since we all know most of these maps don't need to be used, I would say Chucks is probably good, and maybe the base maps. But are the base and base mod maps correct?? I ask mostly because the base mod has alot of timing changes, and they also seem like they are pretty extreme changes from the base stock map. I'm just trying to find some good maps to look at and compare differences in timing.

NeedFD

I've been using Tim Benton's map and it's smooth for the most part, I'll update once i find out the afrs on a dyno or datalogit.

Without actually doing a full 400 cell comparison of IGL, Tim's is the same as the base mod map.
