I had that exact chip previously, made similar numbers to rica, about 280 bhp on my 94 t5 manual, afrs all good, not much below 3.8k but nice above that, ok for a cheapy

I know from speaking with rob the 304/310 remaps (which he has copies of as data / settings) are just tweaking the fuel and ignition timing and very little else.
I would say it's risky buying one, but with the 940s we buy loose chips and fit them from eBay / forum users.
It could be possible that the seller is such a person as a forum user and flashes them on, but obviously that's difficult to tell via Ebay.
I'd suggest getting Oblark to sort a nice progressively mapped M4.4 ECU, works nicely on my T5.
I've seen a 16t make that sort of power and then it died so for a 15g to make 317 bhp .............
The rica maps are just a fuel, ignition and boost increases within the safe boundaries of the standard map.

Well, the boost is not extremely high, on 4th it's 1.4bar in peak and 1bar in the end. Of course, the lifetime of the turbo became less, but not so catastrophic. Such power was gained due to modifications. I'm pretty sure that I can gain a bit more by installing green injectors, raising boost to 1.5bar in peak, tuning the program of the chip and tuning the position of NA cams. But there is no need to do that, because you will bent rods. A month ago I've bent rods on my engine. I raised the boost to maximum 1.7-1.8bar and the car produced around 330-335hp, but after several drag races the engine started to knock. Than I lowered the boost to 1.4 in peak and made a dyno and several drag races with saab. So 317hp was dynode with bent rods Now I'm planning to install H-beam rods, K24 turbo. Yesterday the quaife was installed in gearbox.

Thanx, I cant wait till I'll install k24 turbo. I'm planning to have about 360-370 hp, with quaife it should run pretty nice.

No, didn't do anything with the chip. That's why I'm saying that I can gain a bit more power.
Ooooohh.
The standard ecu is mapped for the standard MAF which gives at 4.9v 826 kg/hr with standard injectors which are 315cc with a injector constant of 1.0
So if you are running a 960 MAF which gives at 4.9v 1107 kg/hr and the 350cc injectors having a injecctor constant of 0.906
I'm running a M4.4 ecu mapped for 3.25" MAF which at 4.9v gives 1603 kg/hr and greens which are 440cc with a constant of 0.7735
I had to run drive my car 7 miles when I had a M4.4 ecu problem with a RICA 304 ecu and it idled rough and drove very lean.
So if you haven't mapped for the larger maf and injectors I would question the 317 bhp reading.

Well, the aim was to get 300hp+ on stock turbo and it was achieved. Next step in tuning will be k24 turbo with m4.4 mapped properly.
